FEATURES AND BENEFITSAcclaimed as the most durable of all resilient-seated butterfly valves in the industry, this valve excels in a wide variety of applications.

Cast in both wafer and tapped-lug patterns in a wide variety of material choices, DEMCO butterfly valves feature a one-piece body for minimum weight and maximum strength. The unique stem hole design in the disc ensures a dry stem journal and the hard-backed seat allows ease of installation, reliable operation, and is field-replaceable without special tools. DEMCO butterfly valves are available in sizes 2 in. through 36 in.(50 mm through 900 mm).

Engineered for long-term, maintenance-free performance, DEMCO butterfly valves are commonly selected for a variety of applications spanning a wide range of industries:

• Chemical and petrochemical

• Agriculture

• Oil and gas drilling and production

• Food and beverage

• Water and waste water

• Cooling towers (HVAC)

• Power

• Mining and materials

• Dry bulk handling

• Marine and government

Bi-directional sealing

This valve provides bi-directional sealing at full rated pressure with identical flow from either direction.

Integral flange seal

Molded into the edge of the seat is an integral flange seal which accommodates ASME weld neck, slip-on, threaded and socket flanges as well as “stub end” type C flanges.

ASME Class 150 rating

Body rating is ASME Class 150 (285 psi non-shock). Wafer body diameters are designed to self-center in ASME Class 150 flange patterns.

FEATURES AND BENEFITSMultiple pressure ratings

Three drop tight pressure ratings are offered for 2 in. to 12 in. (50 mm to 300 mm) sizes.The standard shut off pressure rating is 200 psi, but 285 and 50 psi shut off ratings are also available and where drop tight closure is not required and minimal torque is desired, a throttling rated valve is available. Both the 50 psi and throttling ratings allow for smaller actuators, which can significantly reduce overall installation cost in automated applications. The 14 in. to 36 in. (350 mm to 900 mm) size valves are available in 150 and 50 psi drop tight shut off ratings as well as throttling.

A Dry stem journal eliminates potential for leakage

The DEMCO disc is uniquely designed with a continuous annular raised land around the stem hole and disc edge which presses into the seat flat at every angular position. The resilient seat presses back with a higher specific force than the line pressure, preventing leakage to the stem. In addition, two O-ring ribs are provided in the seat stem bore creating a triple stem seal.In competitive stem seal designs with boot seats, a seal is accomplished by an interference “squeezing” on the stem or an O-ring in the stem journal. The potential for leakage behind the seat is high for this competitive design. As the disc wipes the seat, elongation of the stem seal area allows leakage to collect behind the seat. This condition is eliminated by DEMCO’s dry stem journal and hard-backed seat.

B Hard-backed cartridge seat

The DEMCO cartridge seat is constructed by permanently bonding a resilient elastomer to a rigid backing ring. In addition to superior sealing integrity, this design; 1) makes valve installation easier because no special precautions are required for disc position. This is especially advantageous when installing valves with fail closed actuators; 2) eliminates high torque and premature failure caused by elastomer distortion as found in other non-rigid seat designs;3) simplifies seat replacement because it is slip fitted into the body, with no need for special tools.

C Positively oriented disc

Proper orientation of the stem/disc connection is assured by the rectangular drive. In 2 in. through 24 in. (50 mm through 600 mm) size valves, the disc is permitted to float on the stem to perfectly center in the valve seat. This design enhances drop tight sealing and prolongs service life.

D End-of-line service

Lug body valves may be used in end-of-line service, with downstream piping removed. (Only weld neck or socket flanges can be used for this service). Since upstream pressure is excluded between the flange and the seat face by the exclusive DEMCO flange seal design, there is no effective force to slide the seat downstream. DEMCO 2 in. through 12 in. (50 mm through 300 mm) Lug Butterfly Valves are suitable for liquid service up to 200 psi with downstream piping removed (150 psi 14 in. through 36 in. (350 mm through 900 mm)).Lug body valves are recommended for isolation of pumps, control devices or other system components which may need to be removed for repair or replacement.Lug valves are also suitable for installation at points from which piping expansion may proceed.Such valves are normally blanked with blind flanges, to protect the exposed seats until new piping is attached.

Series NE-I Sanitary

Sizes 2 in. through 12 in. (50 mm through 300 mm), it is similar to our Series NE-I valve, but is exclusively designed to meet the rigorous requirements of sanitary service in the food and beverage industry. The body is available in bronze, stainless steel, aluminum or electroless nickel-coated ductile iron. FDA - approved materials are used for all wetted parts. Handle parts are bronze and stainless steel, permitting caustic washdown.

Other benefits:

• DEMCO dry journal stem seal system gives absolute assurance of sanitary butterfly valve construction.

• Drilled passageways, a design originated by DEMCO, vent the entire interior of the disc to atmosphere. No closed chamber is provided for the culture of undesirable organisms.

• Discs are produced from investment castings, smooth and non-porous. Stem bosses are minimized for increased flow.

• The projecting inner surface of the resilient seat contacts and is compressed by the mating flange to form a smooth and uninterrupted flow way. This positive seal between the innermost contact of the seat and flange ensure aseptic conditions after a piping flush.

Sanitary Features

Series NEI-T Teflon

Because of the inert, aseptic non-stick character of Teflon, DEMCO’s NEI-T Teflon-lined butterfly valve is ideal for “clean” lines in food and beverage plants. The Teflon seat consists of a virgin Teflon liner overlaying and bonded to an elastomer cushion (either Buna-N or EPT are available) which provides resilience for sealing. The Teflon liner extends over the seat faces, completely covering and sealing the resilient material from contact with line fluids.

Marine

DEMCO Marine butterfly valves are available in the NE-C Lug, NE-I Lug and Wafer and NE-D Wafer styles and conform to Title 46 of the Code of Federal Regulations, Part 56 of the U.S. Coast Guard’s Marine Engineering Regulations as well as the American Bureau of Shipping Standard including tagging per MSS-SP-25 and testing per MSS-SP-67.

BUTTERFLY VALVES

DR PISTON ACTUATORSDEMCO Series DR Piston Actuators consist of two opposed pistons with integral gear racks which are coupled to a common central drive shaft to produce rotary motion.

In the basic unit, the Body, Pistons and End Caps are aluminum; the Central Drive Shaft is hard anodized, high performance Aluminum Alloy 70-75. The Fasteners are plated steel; the Seals are Buna-N. All units are totally enclosed and use gaskets for weatherproof operation. Carbon filled teflon guide bands support the pistons to eliminate metal-to-metal contact during actuator operation. As a result, piston O-rings designed for sealing are not required to perform bearing functions.

Mounting the actuator to the valve for many popular sizes is direct, requiring only a splined, aluminum stem adapter. Other sizes may require the addition of an aluminum adapter plate, but still make a closed coupled unit. Some sizes (mostly the larger valves) will require the traditional steel brackets/coupling mounting kit.

Consult the factory for complete data sheets showing mounting configurations. Flatted stems are standard on 2 in. through 12 in. (50 mm through 300 mm) Butterfly Valves (NE-C, NE-I, NE-D), whereas 14 in. through 36 in. (350 mm through 900 mm) NF-C utilize a keyed stem.

Series DR Actuators are available as Double-Acting or Spring Return. Double-Acting is the most economical, requiring either air or hydraulic pressure for opening and closing (fail last position).

Spring-Return Actuators use compression spring(s) to move valve in one direction, while air pressure moves it in the opposite direction.

Spring Return Actuators are used when valves must move to a predetermined position upon air supply failure (fail open or fail closed).

Positioners*Pneumatic positioners are offered for modulating service. The standard signalrange is 3-15 psi, and may begenerated by temperature,pressure or level controllers.

Solenoid Valves*Solenoid Valves are used todirect supply air to the actuatorto open and close the butterflyvalve at the command of an on/offelectrical signal.Direct attachment to the actuator througha manifold eliminates all external piping. Pressure connections are 1/4 NPT. Standard voltage is 120 VAC; other voltages are available on special order.

NEMA 4 weather proof or NEMA 7 explosion-proof enclosures are available.Solenoid valves are available as 3-way valvesfor spring return actuators or 4-way for double acting actuators. Four-way solenoids are equipped with a push button manual override. Exhaust metering valves are available tocontrol opening and closing speed ofthe butterfly valve.

Declutchable ManualWorm Gear OverridesDeclutchable ManualWorm Gear Overridesare available for size40 through 4004 DR actuators.Especially applicable to spring return actuators, the handwheel can be engaged with a special declutch lever to hold the valve in its last position until the actuator isreturned to automatic operation.

3-way adapter assemblies mechanically link two butterfly valves, to close one while opening the other, with a single actuator. Valves are commonly connected in this manner by assembling to a flanged tee for diverting service.

3-way adapters for valves may be used with piston, cylinder, diaphragm, or electric actuators, gear operators or manual handles.

GENERAL TECHNICAL INFORMATION

Pressure RatingThree drop tight pressure ratings are offered for DEMCO Butterfly Valves. Normally, 200 psi shutoff is used in butterfly applications. However, 285 psi shutoff is optionally available for higher pressure applications. For smaller actuator sizing, 50 psi valves offer reduced torque.

For minimum torque, throttling valves, which do not provide drop tight closure, are available.

Vacuum RatingDEMCO Butterfly Valves will seal against 10 microns of vacuum (29.9 inches of mercury). For reduced torque and extended seat life, 50 psi discs are recommended for the dry service conditions found in many vacuum applications.

End-of-Line ServiceLug body valves may be used in end-of-line service, with downstream piping removed. (Weld neck or socket flanges, only, can be used for this service.) Since upstream pressure is excluded between the flange and the seat face by the exclusive DEMCO flange seal, there is no effective force to slide the seat downstream. DEMCO Lug Butterfly Valves are recommended for liquid service up to 200 psi with downstream piping removed.

Lug body valves are recommended for isolation of pumps, control devices or other system components which may need to be removed for repair or replacement.

Lug valves are also suitable for installation at points from which piping expansions may proceed. Such valves are normally blanked with blind flanges, to protect the exposed seats, until new piping is attached.

MarkingEach valve is positively identified by marking and tagging per MSS SP 25.

ActuationPositive latch handles, worm gear operators and automatic actuators are available and totally interchangeable on the DEMCO valve.

The DEMCO top flange is dimensionally compatible with other competitive butterfly valves. With optional “utility top” stem, the DEMCO valve interchanges directly with competitive valves, allowing valve replacement without the need for new actuation.

Installation and MaintenanceDEMCO Butterfly Valves are bi-directional, with identicalflow-way from either face. To install, simply close the valve, insert between flanges and make up with studs or cap screws. No regular maintenance or lubrication is ever required. Disassembly is simple, for inspection or replacement of parts.Open the valve, remove handle or actuator, remove tangential pins, pull out the stems and push the disc and seat out of the body. Reassemble in reverse order, with a small amount of general purpose non-hydrocarbon based lubricant on the outside of stems, seat and disc flats.

Steel or cast iron flanges of either raised or flat-faced type are suitable for use with DEMCO Butterfly Valves. Plastic flanges are subject to damage at installation by over-tightening the bolting and may deflect or “cup,” resulting in flange leaks. Refer proposed plastic flange installations to DEMCO Valve Quotations Department for review and recommendation.

Throttling discs, with no seat interference, do not provide a stem seal. Stem O-rings are provided for this application. Flange gaskets assist the O-rings in 2 in. through 12 in.(50 mm through 300 mm) valves, and must be used with throttling discs, only.

GENERAL TECHNICAL INFORMATION

This nomograph gives corresponding values for the parameters of flow rate, valve size, disc angle and pressure drop of DEMCO Butterfly Valves in 1.0 specific gravity water service at 68°F (20°C).

The lower right-hand corner of the graph with heavy line border represents line velocities below 15 feet per second and is normally used for valve sizing in liquid applications.

Butterfly Valves are economical throttling devices. Reliable throttling can be attained at disc openings from 25° to 70°.

Sample Computation for WaterWater, with specific gravity of 1.0 and flow rate of 1200 gpm, through 6 in. (160 mm) Butterfly Valve. Required: Pressure drop at full and 75° disc opening.

Project horizontally from 1200 gpm to 6 in. (150 mm) valve curve.Project vertically upward to full open valve curve, then horizontally to read 0.35 psi pressure drop.Continue upward projection to intersect 75° opening curve, then horizontally to read 0.8 psi pressure drop.

Sample Computation for AirAir, with density of 0.217 lbs./cu. ft., flow rate of 40,000 cu. ft./hr., through 5 in. (125 mm) Butterfly Valve. Required: Pres-sure drop through full open valve.

Disregarding change in gas condition by pressure drop across valve, proceed from 40,000 cu. ft./hr., as in liquid computation, to read 15 psi pressure drop. Convert pressure drop from water to air by multiplying this value times the ratio of air-to-water densities:

To determine pressure drop for any fluid, multiply value obtained from the nomograph by the quotientof the fluid density, in pounds percubic foot, divided by 62.4.

Water HammerWater hammer is a series of shocks in a piping system caused by rapidly stopping the flow of fluid in that system.Although it is difficult to measure pressure spikes caused by water hammer shock with ordinary equipment, maximum obtainable pressures caused by instantaneous valve closure can be approximated by the following formula:

Pressure (max) = Interrupted velocity (fps) x 58 psi/fps

In other words, pressure increases 58 psi for each foot per second of interrupted pipe line velocity.

A pipe carrying fluid at 15 feet per second velocity will have an instantaneous pressure increase of 870 psi under rapid closure conditions.

The effects of water hammer are seen in a butterfly valve as bent disc and stems, broken bodies or both.Water hammer can be minimized or eliminated by slowing valve closure time in accordance with the following formula:

Time seconds =

Where:Q = Flow in gpm.S = Upstream pipe size in sq. ft.P = Pressure rating of the valve in psi.

Generally, a closing time of 6 to 8 seconds is sufficient to eliminate water hammer.

Cavitation DataLiquid flow is accelerated as it passes through a valve in sucha manner that pressure is decreased below the vapor pressure and bubbles form. Immediately downstream of the valve, velocity decreases while pressure increases and the bubbles collapse causing noise and possible mechanical damage to the valve and piping. This is called cavitation.

Cavitation can often be identified by the noise of the collapsing bubbles which sounds like gravel flowing in the pipe.

Generally butterfly valves operate with high flow capacities and at low pressure differentials and are not particularly susceptible to cavitation.

When butterfly valves are used as control valves, one can assure that cavitation will not occur by applying the following simplified formula:

GENERAL TECHNICAL INFORMATION

DPmax = K (P - P ) C 1 V

Where:

DPmax = Differential pressure across the valve.

K = Cavitation constantC

(approximately .35 for butterfly valves).

P = Inlet pressure (psia).1

P = Vapor pressure of the flowing liquid (psia).V

Example:What is the maximum pressure drop possible through a butterfly valve at 100 psig inlet pressure with water at 68°F (.339 psia vapor pressure)?

DPmax = K (P - P ) C 1 V

Under the above conditions it is possible to take a 40.03 psi pressure drop across the valve before cavitation will begin.

TorqueThe torque (turning effort) required to operate a given butterfly valve is determined by two factors: friction of disc and seat due to interference, and dynamic forces of flow through the valve which tend to open or close the valve. Actuator torque output must meet or exceed the maximum torque requirement of the valve.

Normal Wet Opening Torque requirements due to interference are tabulated below. Dry service will increase opening torque significantly. Consult factory for dry service torque requirements

The disc of a butterfly valve, in partially opened condition, is subject to “lift” forces from passage of fluid over its surfaces. This effect is analogous to an airplane wing and results in an unbalanced turning force on the disc. Dynamic torque is proportional to pressure drop through the valve and may become significant in some applications.

Dynamic torque typically is a maximum at about 70° disc opening. Under high differential pressure conditions, such torque may exceed the design strength of stems, connections or actuators. The curves at right may be used to calculate dynamic torque for DEMCO Butterfly Valves and should be consulted in any case where high differential pressure may occur during operation of a valve.

Buna N is a general purpose elastomer compounded for maximum hydrocarbon or petroleum resistance. 0°F to+180°F Same as Nitrile, Hycar*, NBR

General Service EPT is recommended for water service. Resistance to saturated steam to 275°F is excellent. EPT is suitable in alkaline solutions. EPT is not suitable for oil or hydrocarbons. Peroxide cured +20°F to +275°F

Food Grade EPT is formulated in compliance with FDA guidelines published in the Code of Federal Regulations, Title 21, paragraph 177.2600. This material is suitable for food service, except milk and edible oils. Peroxide cured +20°F to +275°F Sulfur cured -30°F to +225°F Same as EPDM, Nordel*

Black Neoprene complies with FDA guidelines and is principally recommended for food and beverage service. It is resistant to vegetable oils, brine and oxygen.0°F to +180°F Same as Polychloroprene, CPE

White Neoprene complies with FDA guidelines and offers chemical resistance comparable to black neoprene but uses fillers other than carbon black to provide white coloration. Physical properties are not as good as black neoprene, and white neoprene should be used only when black cannot be tolerated. Storage should be under low light conditions to prevent discoloration. 0°F to +180°F

Hypalon* is compounded for chemical resistance and is excellent in acids and hydrocarbons. 0°F to +180°F Same as CP

Viton* is excellent at elevated temperatures and also in harsh chemical environments. Viton is not suitable for hot water or steam. +20°F to +300°F Same as Fluoroelastomer

Natural Rubber is generally superior to other elastomers in abrasion resistance and is recommended for dry material handling. Use in oils and solvents is not recommended. -30°F to +150°F

Fluorosteam seats offer heat and chemical resistance to hydrocarbons and hot water or saturated steam. Maximum temperature capability is dependent on fluid resistance, pressure and flow rates. +20°F to +275°F

ETM-30230 is compounded to combine many of the better media properties of Buna-N, EPT or Neoprene for service in hydrocarbons, gasoline, solvents, animal oils and vegetable oils with a wide temperature range (–30°F to 230°F). Abrasion resistance is equal to Buna-N. Resistance to hydrogen sulfide and carbon dioxide are superior to Buna-N. -30°F to +230°F

NEI-T Teflon* SEAT is Buna-N, or EPT elastomer bonded to a virgin TFE covering providing an inert, aseptic non-stick surface which is excellent for sanitary food service applications. 0°F to +250°F

CAMERON AND COOPER CAMERON VALVES TERMS AND CONDITIONS OF SALE1. CONTRACT ACCEPTANCE:Any written or oral purchase order received from Buyer by Cooper Cameron Corporation, Cameron Division and Cooper Cameron Valves (“Seller”) shall be construed as a written acceptance of Seller's offer to sell and shall be filled in accordance with the terms and conditions of sale set forth herein. SELLER'S ACCEPTANCE OF THIS ORDER IS EXPRESSLY CONDITIONED ON BUYER'S ASSENT TO THE TERMS CONTAINED HEREIN. The terms and conditions of Seller's proposal (if any) and acknowledgement shall prevail over any conflicting or different terms in Buyer's order unless Buyer notifies Seller in writing of its objections thereto within fifteen (15) days from receipt of Seller's acknowledgement. Buyer's standard terms of purchase will not be considered a counteroffer to Seller's terms and conditions of sale. The failure of Seller to object to any provision in conflict herewith whether contained on Buyer's purchase order or otherwise shall not be construed as a waiver of the provisions hereof nor as an acceptance thereof.

2. QUOTATIONS AND PRICES:All quotations are made for prompt acceptance and any terms quoted therein are subject to change without notice after thirty (30) days from the date quoted unless specifically stated otherwise on the quotation. Any product, service capability or manufacturing capability which may be available at the time a quotation is made is subject to prior sale. Prices quoted are valid for thirty (30) days unless specifically stated otherwise on the quotation and are subject to change without notice. The price in effect at the time of shipment including any escalation formula will apply, unless a valid quotation or written agreement to the contrary exists between Buyer and Seller. All prices shown are in U.S. dollars and are F.O.B. Seller's shipping point. Seller reserves the right to place a service charge on past due accounts at the highest rate permitted by law. Any documentation pertaining to traceability requirements for raw materials or products or documentation required for any routine or special processes must be identified by the Buyer at the time of quotation (if any) or at the time of order placement.

3. TAXES:Any tax or other charge imposed by law on the sale or production of goods or the performance of services shall be paid by the Buyer, unless the law specifically provides that such payment must be made by Seller, in which case Buyer shall reimburse Seller for such payment as part of the purchase price. Custom duties, consular fees, insurance charges and other comparable charges will be borne by Buyer.

4. SHIPPING SCHEDULE AND DELIVERY:Shipment schedules are given as accurately as conditions permit and every effort will be made to make shipments as scheduled. Seller will not be responsible for deviations in meeting shipping schedules nor for any losses or damages to Buyer (or any third party) occasioned by deviations in the shipping schedule, whether due to Acts of God, orders bearing priority ratings established pursuant to law, differences with workmen, local labor shortages, fire, flood, shortages or failure of raw materials, supplies, fuel, power or transportation, breakdown of equipment or any other causes beyond Seller's reasonable control, whether of similar or dissimilar nature than those enumerated. Seller shall have additional time within which to perform as may be reasonably necessary under the circumstances and shall have the right to apportion its production among its customers in such a manner as it may consider to be equitable. Seller reserves the right to furnish commercially equivalent or better substitutes for materials or to subcontract the Buyer's order or portions thereof as Seller deems necessary. In no event shall Seller be liable for any consequential damages resulting from failure or delay in shipment. If Buyer requires drawings, procedures, standards or similar material for approval, shipping schedules will be calculated from the time such approvals are received by Seller, since shipping schedules are based on Seller having all required information and a firm order from Buyer which is enterable into production. Any hold points, witness points or the need for inspection by Buyer's representatives must be identified by Buyer at the time of quotation (if any) and/or order placement in order that the effect on the prices or shipping schedules (if any) can be taken into account. Additional inspection or testing required by Buyer which affects normal production sequence will be considered as extending the shipping dates accordingly.

5. MINIMUM BILLING:Seller reserves the right to impose a minimum billing charge on all sales, change orders or order supplements.

6. TERMS OF PAYMENT:Terms of payment are 30 days from date of invoice unless otherwise stated in the quotation or Seller's order acknowledgment.

7. CANCELLATIONS AND RETURNS:Purchase orders once placed by Buyer and accepted by Seller can be canceled only with Seller's written consent and upon terms which will save Seller from loss. No products may be returned for credit or adjustment without written permission from Seller's office authorized to issue such permission.

8. WARRANTIES:All products of Seller's manufacture except for its Orbit product are warranted against defects of material and workmanship for a period of twelve (12) months from the date of installation or eighteen (18) months from date of shipment, whichever period first expires while its Orbit product is warranted for thirty six (36) months from date of shipment, when all such products are used in the service and within the pressure range for which they were manufactured. In the case of products or parts not wholly of Seller's manufacture, Seller's liability shall be limited to the extent of its recovery from the manufacturer of such products or parts under its liability to Seller. Any repair work performed by Seller is warranted for one year from completion of such repairs and applies only to work performed. If, within these specified periods, Seller receives notice from Buyer of any alleged defect in or nonconformance of any product or repair and if in the Seller's sole judgment the product or repair does not conform or is found to be defective in material or workmanship, then, Buyer shall, at Seller's request, return the part or product F.O.B. to Seller's designated plant or service location. Seller has no liability for removal or reinstallation of products or equipment. Seller, at its option and expense, shall repair or replace the defective part or product, or repay to Buyer the full price paid by Buyer for such defective part, repair or product. Any repayment of purchase price shall be without interest. Seller's warranty liability, including defects caused by Seller's negligence, shall be limited to such repair, replacement or refund, and shall not include claims for labor costs, expenses of Buyer resulting from such defects, recovery under general tort law or strict liability or for damages resulting from delays, loss of use, or other direct, indirect, incidental or consequential damages of any kind. Seller will not be responsible for failures of products which have been in any way tampered with or altered by anyone other than an authorized representative of Seller, failures due to lack of compliance with recommended maintenance procedures or products which have been repaired or altered in such a way (in Seller's judgment) as to affect the products adversely. THIS WARRANTY IS EXPRESSLY IN LIEU OF ALL OTHER WARRANTIES, EXPRESS, STATUTORY OR IMPLIED, INCLUDING THE WARRANTY OF MERCHANTABILITY AND FITNESS FOR PARTICULAR PURPOSE WHICH EXCEED THE FOREGOING WARRANTY.

9. NUCLEAR SALES:The products sold hereunder are not designed or manufactured for use in or with any atomic installation or activity. If the Buyer or ultimate user of these products intends to use them in such an installation or activity, Seller's Nuclear Terms of Sale shall be part of and control this contract. Seller will furnish Buyer with a copy of its Nuclear Terms of Sale upon request.

10. PATENT INFRINGEMENT:Seller warrants that the use or sale of material or apparatus sold or rented by it to Buyer hereunder will not infringe United States' patents of others covering such material or apparatus by itself, and hereby agrees to indemnify Buyer against judgment for damages for such infringement of any such patent, provided that Buyer shall, upon receipt of any claim for infringement of any such patent or threat of suit for such infringement or upon the filing of any suit for infringement, whichever comes first, promptly notify Seller in writing and afford Seller full opportunity, at its option and its own expense, to answer such claim or threat of suit, assume the control of the defense of said suit, and settle or compromise same in any way Seller sees fit. Other than court--awarded judgments as aforesaid Seller shall not be liable for any delays, loss of use or for other direct, indirect, incidental or consequential damages incurred by reason of any such judgment. Seller does not warrant that such material or apparatus (a) will not infringe any such patent when not manufactured by or for Seller or when specially made in whole or in part to the Buyer's design specification and such infringement arises from the inclusion of such specified design or (b), if used or sold in combination with other material or apparatus, or if used in the practice of a process, will not, as a result of such combination or use, infringe any patent covering such combination or process; and Seller shall not be liable for and does not indemnify Buyer for damages or losses of any nature whatsoever resulting from actual or alleged patent infringement arising pursuant to (a) or (b) above.

11. SELLER'S RIGHT TO MANUFACTURE:Seller in its sole discretion shall have the right to manufacture the products provided hereunder as far in advance of its estimated shipping schedule as it deems appropriate. Seller expressly reserves the right to change or modify the design and construction of any product in due course of Seller's manufacturing procedure without incurring any obligation or liability to furnish or install such changes, modifications or improvements to products previously or subsequently sold.

12. ENGINEERING AND SERVICE:Upon request, Seller will provide engineering and/or technical information regarding its products and their uses and, if feasible, will provide personnel to assist Buyer in effecting field installations and/or

field service. Any such information, service or assistance so provided, whether with or without charge, shall be advisory only. In that regard, neither Seller nor Buyer assumes any liability for the acts or omissions of the other party except as may be provided in these terms.

13. LABOR STANDARDS:Seller hereby certifies that these products were produced in accordance with all applicable requirements of Section 6, 7 and 12 of the Fair Labor Standards Act as amended and of regulations and orders of the United States Department of Labor issued under Section 14 thereof.

14. INSPECTION:Unless otherwise agreed in writing, final inspection and acceptance of products must be made at Seller's plant or other shipping or receiving point designated by Seller and shall be conclusive except as regards latent defects. Buyer's representatives may inspect at the Seller's plant or shipping point during working hours prior to shipment in such manner as will not interfere with operations.

15. DELIVERY AND ACCEPTANCE:Delivery shall be in accordance with the requirements in the Purchase Contract, provided, in the event Buyer is unable to accept delivery upon completion of the manufacture of the Goods in accordance with such requirements, Buyer agrees that (i) title and risk of ownership shall pass to Buyer on date of Seller's invoice, and (ii) Buyer will make payments within thirty days after date of such invoice. Seller shall retain custodial risk of loss until delivery is made in accordance with such requirements.

16. TRANSPORTATION CHARGES, ALLOWANCES, CLAIMS:All prices are F.O.B. Seller's plant or other designated shipping point. No freight is allowed unless stated in Seller's quotation (if any) or in a written contract which may exist between Seller and Buyer at the time of shipment. If Seller's quotation or a written contract states that all or a portion of freight is allowed, all prices are F.O.B. Seller's plant or other designated shipping point, with most economical surface transportation allowed. If the quoted or contractual price includes transportation, Seller reserves the right to designate the common carrier and to ship in the manner it deems most economical. Added costs due to special routing requested by the Buyer are chargeable to the Buyer. Under no circumstances is any freight allowance which is absorbed by Seller to be deducted from the selling price. If the quoted price or contract includes transportation, no deduction will be made in lieu thereof whether Buyer accepts shipment at plant, warehouse, freight station, or otherwise supplies its own transportation. When sales are made from the Seller's warehouse, Seller reserves the right to charge either actual or pro-rated freight from Seller's principle point of manufacture to Seller's warehouse. Buyer assumes risk of loss upon delivery to the carrier, regardless of who pays shipping costs. Seller endeavors to pack or prepare all shipments so that they will not break, rust or deteriorate in transit, but does not guarantee against such damage. Unless requested in writing by the Buyer, no shipments are insured by Seller against damage or loss in transit. Seller will place insurance as nearly as possible in accordance with Buyer's written instructions but in such case Seller acts only as agent between the insurance company and the Buyer and assumes no liability whatsoever. Any claims for shipping loss, breakage or damage (obvious or concealed) are Buyer's responsibility and should be made to the carrier. All claims regarding shortages must be made within thirty (30) days from receipt of shipment and must be accompanied by the packing list(s) covering the shipment.

17. CONSULAR INVOICES:Consular fees for legalizing invoices, stamping bills of lading, or other documents required by the laws of any country or destination are not included in quotations or selling prices. If instructed in writing, Seller will make arrangements for consular documents and declarations as agent of the Buyer, but Seller assumes no liability whatsoever as a result of making such arrangements. Seller assumes no responsibility for any fines or other charges imposed due to errors or incorrect declarations.

18. INDEMNIFICATION AND LIMITATION OF LIABILITY:A. INDEMNIFICATION:(1) Seller shall release and indemnify Buyer and hold Buyer harmless for
