Fisher� EZ Sliding-Stem Control ValveFisher EZ valves (figures 1 and 2) are used forthrottling or on-off control of a wide variety of liquidsand gases. The single-port, globe-style body designoffers quick-change trim and a post-guided,unbalanced valve plug. The EZ valve is used inchemical or hydrocarbon processing applications orwherever control of non-lubricating, viscous, or otherhard-to-handle fluids is required.
Metal-to-metal seating is standard for all generalapplications over a wide range of pressure dropsand temperatures. Metal-to-PTFE seating is optionalfor stringent shutoff requirements.
The easy-e� Valve Family
EZ valve bodies are part of the versatile easy-efamily of industrial control valves. easy-e valvebodies share the following characteristics:
� Multiple trim material choices
� Trim temperature capability with standard metalseats to 427�C (800�F)
� FGM gaskets
� Interchangeable, restricted-capacity trims andfull-sized trims to match variable process flowdemands

� Different valve plug styles that provideparticular flow characteristics for highly-specializedapplications. Standard plugs are available with thefollowing flow characteristics:
� quick-opening� linear� equal percentage
� Optional constructions allow materialcompatibility with NACE MR0175 / ISO 15156 andMR0103. Contact your Emerson ProcessManagement sales office for details.
� 316 stainless steel packing box parts arestandard (including packing flange, studs, and nuts)
Features� Trim Designed for Stability—Post guiding
provides valve plug stability with less chance of asticking valve plug due to non-lubricating or stickyprocess fluids or build-up of entrained solids. Postguiding stabilizes the valve plug at all points in itstravel range to reduce vibration, mechanical noise,and trim wear.
� Performance+ Seat Ring—Flow-straightening,vaned seat ring is available in full port and firstreduction port sizes. It offers excellent open- andclosed-loop performance and may be used as adirect replacement for the non-vaned seat ring. TheFisher valve division recommends that thePerformance+ seat ring be used for non-viscous,flow-up, liquid applications.
� Compliance with the Clean Air Act—ENVIRO-SEAL packing systems (figure 4) thatprovide an improved stem seal to help prevent theloss of process fluid are available. These packingsystems feature PTFE, Graphite ULF, or duplexpacking with live-loading for reduced packingmaintenance.
� Reliability—The process fluid flows throughthe trim, flushing away solid deposits above andbelow the guide bushing, thus reducing thepossibility of a sticking valve plug.
� Easy Maintenance—Quick-change trim, with aclamped-in seat ring, reduces the disassembly time.The valve body can stay in the pipeline duringremoval of trim parts for inspection or maintenance.
� Application Flexibility—Low-flowrequirements can be satisfied with standardrestricted-capacity trim or with Micro-Form,Micro-Flute, or Micro-Flow valve plugs. If flowrequirements change, the valve can be converted tofull-sized trim.
� Economy—Streamlined flow passages providegreater capacities than most globe valves of thesame line size.

� Compliance with European Standards—Valves are available with dimensions specified byEN/DIN standards. See figure 7.
� Sour Service Capability— Unless otherwisenoted, references are to NACE MR0175-2002.Optional materials are available to meet NACEMR0103 and NACE MR0175 / ISO 15156. Materialrequirements under these standards vary by editionand year of issue; the specific standard must bespecified.
ENVIRO-SEAL, HIGH-SEAL Packing SystemsENVIRO-SEAL and HIGH-SEAL packing systems
offer exceptional sealing capabilities. These systemseasily install in your existing valves or can bepurchased with new valves. These systems offer animproved method of sealing your process toconserve valuable process fluid. The long-life andreliability of these systems also help to reduce yourmaintenance costs and downtime.
For applications requiring compliance withenvironmental protection regulations, the uniqueENVIRO-SEAL packing system (figure 4) and, forhazardous service, the ENVIRO-SEAL bellows sealsystem (figure 3) are offered. The emission controlpacking system helps to keep emissionconcentrations below the EPA 100 ppm requirement.

For an excellent stem seal in applications that arenot environmentally-sensitive, the HIGH-SEALGraphite ULF packing system (figure 4) is offered.The HIGH-SEAL packing system provides excellentsealing at pressure/temperature ratings beyondENVIRO-SEAL limits. ENVIRO-SEAL systems mayalso be applied for excellent stem sealing in higherpressure/temperature applications not requiring EPAcompliance.
ENVIRO-SEAL packing systems, available withPTFE, Graphite ULF, or duplex packing, and theHIGH-SEAL Graphite ULF packing system featurelive-loading and unique packing-ring arrangementsfor long-term, consistent sealing performance.
ENVIRO-SEAL, HIGH-SEAL Features
� Excellent Sealing Capabilities—The packingsystem provides excellent sealing, guiding, andtransmission of loading force. The excellent sealingof the ENVIRO-SEAL system can control emissionsto below the EPA (Environmental Protection Agency)minimum of 100 ppm (parts per million).
� Improved Service Life—ENVIRO-SEAL andHIGH-SEAL system design, very smooth stemsurface, and live-loading combine to give you longservice with very low maintenance. The externallive-loading provides a constant load over the life ofthe packing material, which greatly reduces yourneed for packing box adjustment and maintenance.
� Easy Installation in Existing Valves—Allparts needed to install the systems in existing valvesare available in a convenient kit.

� Adaptable to Many Applications—ENVIRO-SEAL systems are available with PTFE orGraphite ULF packing for 9.5 through 31.8 mm (3/8through 1-1/4 inch) diameter valve stems.HIGH-SEAL systems with Graphite ULF packing areavailable for 9.5 through 50.8 mm (3/8 through2-inch) diameter valve stems. StandardENVIRO-SEAL packing systems can be used invacuum service with packing rings in standardorientation. It is not necessary to reverse theENVIRO-SEAL PTFE packing rings.

Micro-Flute Valve Plugs for MinimumLeakageThe EZ valve can be furnished with PTFEcomposition-seat Micro-Flute valve plugs for Class VIshutoff per ANSI/FCI 70-2 and IEC 60534-4.
These valve plugs are available on NPS 1/2 to 2
valves with a 9.5 mm (3/8 inch) stem diameter, 9.5mm (3/8 inch) actuator-stem connection, and 6.4 mm(0.25 inch) seat ring port diameter. These plugshave the same flow coefficients as standardMicro-Flute plugs. Standard seat rings are used.
The valve plugs have a screwed retainer that holdsthe seat disk and valve plug tip to the valve stem.

When using any packing at low process temperatures,a cast extension bonnet may have to be used to prevent packing damage which could result from the formation of valve stem frost. Material selection for trim and other components willalso be limiting factors.

The trim may be further limited by maximum pressure drops listed in tables 9 and 10.4. Pressure drops at intermediate temperatures may be interpolated.5. Maximum temperature capability of PTFE-coated N04400 gaskets as used in gasket set 3 is 149�C (300�F).
