Gases are used in chemical and industrial processes, such as analytical instrumentation, environmental compliance, electronic manufacturing, chemical production, reference gases, and medical uses. All the devices in these systems must be compatible to prevent complications, such as corrosion, unwanted chemical reactions, ignition, or explosion. Also, some of these process systems operate at very high or very low temperatures. Regulators must be constructed to withstand these temperatures.

The regulators and relief/backpressure regulators covered in this section are available in materials that are chemically compatible with most process gases. The products shown in the Air, Liquids, and Sanitary sections may also be used in your system if the materials are compatible.

Process Gases aPPlications

IntRodUctIon

Chemical and processing plants use various gases in their process systems. Many of these gases require regulator materials that eliminate or reduce corrosion that can contaminate the system and to increase the service life of the regulator. This Application Guide briefly explains the types of regulators and the construction materials available for these regulators.

REgUlatoR tYPESPressure Reducing Regulators

In some process gas applications, the pipeline pressure may need to be reduced for a process or piece of equipment. Depending upon the accuracy required by the application, a direct-operated or pilot-operated regulator can be used to reduce the gas pressure.

Direct-operated regulators are used for lower flow rates. Pilot-operated regulators are used for high flow rates or where precise pressure control is required.

differential/Bias Regulators

A differential or bias regulator maintains a pressure difference between two locations in the system.

Relief Valves/Backpressure Regulators

A relief valve or backpressure regulator opens when the upstream controlled pressure increases above the setpoint. Relief valves and backpressure regulators are the same devices. The name is determined by the application. Overpressure protection is provided by relieving pressure when it rises above the setpoint. When upstream pressure rises above the setpoint, the relief/backpressure regulator opens to allow excess upstream pressure to flow downstream, typically into a pressurized system or to atmosphere.

Vacuum Breakers vs. Vacuum Regulators

There are a variety of terms used to describe vacuum, causing confusion when communicating with someone that uses different terminology. Emerson uses the following vacuum terminology:

First, determine whether the units are in absolute pressure or gauge pressure (0 psig or 0 barg is atmospheric pressure).

For example:• 5 psig (0,34 barg) vacuum is 5 psi (0,34 bar) below atmospheric pressure

• -5 psig (-0,34 barg) is 5 psi (0,34 bar) below atmospheric pressure

• 9.7 psia (0,67 bara) is 9.7 psi (0,67 bar) above absolute zero or 5 psi (0,34 bar) below atmospheric pressure (14.7 psia - 5 psi = 9.7 psia or 1,01 bara - 0,34 bar = 0,67 bara).

Just as there are pressure reducing regulators and pressure relief valves for positive pressure service, there are two basic applications for vacuum service. The terms used for each are sometimes confusing. Therefore, it is sometimes necessary to ask further questions to determine the required function of the regulator. Emerson uses the terms vacuum breaker and vacuum regulator to differentiate between the two types.

Vacuum Breakers

Vacuum breakers limit the increase in vacuum. An increase in vacuum (decrease in pressure) beyond the setpoint is sensed on the diaphragm causing the disk to move away from the seat. This permits a higher pressure to enter the system and restore the controlled vacuum to its original pressure setting.

Vacuum Regulators

Vacuum regulators maintain a constant vacuum at the regulator inlet. A decrease in vacuum (increase in pressure) beyond the setpoint registers on the diaphragm causing the disk to move away from the seat, allowing a higher vacuum source to restore the vacuum to its original setting.

aPPlIcatIonS

In many cases, piping systems are required to transport the process gas from its storage location outside of the building to the point(s) where it is required within the building. Process gases are supplied from pipelines, cylinders, or pressurized tanks. Regulators are used to reduce the pressure to a level that is compatible with the supply pressure design parameters of the downstream system. A combination of regulators and relief valves/backpressure regulators may be required to accomplish these objectives.

conStRUctIon MatERIalS

Each process gas has its own set of unique characteristics in terms of its chemical composition, corrosive properties, impurities, flammability, hazardous nature, toxic effect, explosive limits, and molecular structure. In some cases special care must be taken to select the proper materials that will come in contact with the process gas.

Material selection for oxygen regulators, for example, must be carefully selected or a fire could result. Oxygen regulators must also be “de-greased or cleaned for oxygen service.”

Typical materials for regulator bodies are cast iron, steel, aluminum, brass, and stainless steel. Monel® and Hastelloy C® are available in some regulators. Trim materials are typically stainless steel, aluminum, or special alloys as mentioned above. The elastomeric parts (diaphragm, disk, and O-rings) are usually Nitrile (NBR) or Neoprene (CR). Other elastomers, such as Ethylenepropylene (EPDM), Fluoroelastomer (FKM), Perfluoroelastomer (FFKM), and PTFE, are also available.

All properties of the process gas should be known and a metals corrosion chart should be consulted to ensure the proper selection of the metal parts that come in contact with the gas. Likewise, an elastomer compatibility chart should be consulted for similar issues. An abbreviated version of these charts follows this Application Guide; the complete versions are in the Technical Reference section of this Application Guide.

It should be noted that a mixture of two or more chemicals may be more or less corrosive than one of the chemicals alone. Rely on past experience when selecting materials for handling a chemical mixture. The charts on the following pages do not address chemical concentrations and mixtures which can affect the corrosion rate.

MatERIal gUIdElInES foR gaSEoUS oxYgEn SERVIcE

All organic and inorganic materials will react with gaseous or liquid oxygen at certain pressures and temperatures. The reaction that occurs can cause a fire or an explosion. Because of these inherent dangers, process system design and valve material selection are extremely important.

247


Oxygen service has many inherent hazards and requires careful and knowledgeable design of the process system. The information and guidelines presented here are intended to help the user; however, other factors, such as service conditions and process system design, must be considered to properly select materials that will handle this gas in a safe manner.

Many of the materials commonly used in valves have ignition temperatures above the normal flowing temperatures of gaseous oxygen. Ignition of these materials by normal flowing temperatures is generally not the danger. The danger is in the ignition of these materials by abnormal, localized high temperature. This list has been compiled from the best information available, but does not necessarily contain all the hazardous conditions that might be encountered in oxygen service applications.

flow Velocity

All valve materials should be suitable for oxygen service, and material selection should meet the velocity criteria, such as set by the Compressed Gas Association Pamphlet G-4.4 (copies can be obtained from Compressed Gas Association, Inc., 500 Fifth Avenue, New York, NY 10036). In general, if the velocity through the port of the valve can exceed 200 feet per second (61 meters per second), only copper-base alloy material should be used for valve body and trim parts in contact with the flow stream.

foreign Particle Impingement

A foreign particle, such as weld spatter, that is being carried in the flow stream and that strikes the valve trim or the valve body wall might have its kinetic energy transformed into sufficient heat to raise the impinging particle or the material it strikes to its respective ignition temperature.

Ignition by already-Burning Material

An organic valve disk, for example, that has already been ignited by foreign particle impingement will release sufficient heat to ignite surrounding metallic materials, thus initiating a serious fire.

Vibration

A part that is caused to vibrate, usually by the flowing velocity, might generate enough heat from internal friction to raise its temperature to its ignition point.

Rapid compression of gas

Opening a valve to pressure the downstream system will result in the compression of the gas in the downstream system. If this is done rapidly, it can result in abnormally high gas temperatures, which might ignite material in the valve and piping system.

Static Electricity discharge

The flow of gas across the trim of a ball, butterfly, or eccentric disk valve might generate a static charge on the trim. Because these valves inherently do not have a good grounding path from the trim to the valve body or from the valve body to the pipeline, use proper provisions and care for their grounding. Failure to do this might allow a discharge spark between the trim and valve body or between the valve body and adjacent piping, igniting the surrounding material.

conclusion

The list shows that many of the hazards arise from the velocity of the flowing gas. For this reason, it is imperative that the system be designed such that flowing velocities will be low.

organic Materials

Organic materials have ignition temperatures below those of metals. Use of organic materials in contact with oxygen should be avoided, particularly when the material is directly in the flow stream. When an organic material must be used for parts, such as valve seats, diaphragms, or packing, it is preferable to select a material with the highest ignition temperature, the lowest specific heat, and the necessary mechanical properties.

Lubricants and sealing compounds should be used only if they are suitable for oxygen service and then used sparingly. Ordinary petroleum lubricants are not satisfactory and are particularly hazardous because of their high heat of combustion and high rate of reaction.

The approximate ignition temperatures in 2000 psig (138 bar) oxygen for a few organic materials are shown in the following table.

Neoprene and Nitrile (NBR) 300 149

Metals

The selection of metals should be based on their resistance to ignition and rate of reaction. Following is a comparison of these two properties for some commonly used valve materials.

Resistance to Ignition in oxygen

Materials are listed in order from hardest to ignite to easiest to ignite. • Copper, copper alloys, and nickel-copper alloys (such as Monels)—most resistant • Stainless steel (300 Series) • Carbon steel • Aluminum—least resistant

Rate of Reaction

Materials are listed in order from slowest rate of combustion to most rapid rate of combustion. • Copper, copper alloys, and nickel-copper alloys (such as Monels)—do not normally propagate combustion • Carbon steel • Stainless steel (300 Series) • Aluminum—burns very rapidly

Note that stainless steel, once ignited, burns more rapidly than carbon steel. Nevertheless, the austenitic grades (300 Series) of stainless steel are considered to be much better than carbon steel because of their high resistance to ignition.

95H Series Pressure Reducing Regulators

264


Introduction

The 95H Series regulators are compact,rugged, direct-operated, pressure reducing regulators. The units are available in 1/4-inch and 1/2 through 2-inch (DN 15 through 50) body sizes and are offered with several different end connection configurations. They are designed to handle inlet pressures up to 600 psig (41,4 bar) and temperatures from -40° to 650°F (-40° to 343°C).

The Type 95HD differential pressure reducing regulator uses spring force to maintain a pressure differential between the spring case loading pressure and regulator outlet pressure.

Regulator Tip

Droop is the reduction of outlet pressure experienced by pressure-reducing regulators as the flow rate increases. It is stated as a percent, in inches of water column (mbar) or in pounds per square inch (bar) and indicates the difference between the outlet pressure setting made at low flow rates and the actual outlet pressure at the published maximum flow rate. Droop is also called offset or proportional band.

95l Series Pressure Reducing Regulators

273


Introduction

The 95L Series regulators are compact, rugged, direct-operated low-pressure regulators for outlet pressures of 2 to 30 psig (138 mbar to 2,1 bar). The units are available in 1/4 and 1/2 through 1-inch (DN 15 through 25) sizes are offered in several different end connection configurations. These regulators are designed to handle inlet pressures up to 300 psig (20,7 bar) and temperatures from -40° to 450°F (-40° to 232°C).

The Type 95LD low-pressure regulator uses spring force to maintain a pressure differential between the spring case loading pressure and regulator outlet pressure.

1. To obtain capacities for regulators using metal diaphragms, multiply the table values by 0.8.

Regulator TipWhen a regulator appears unable to pass the published flow rate, be sure to check the inlet pressure measured at the regulator body inlet connection. Piping up to and away from regulators can cause significant flowing pressure losses.

98l Series Backpressure/Relief Valves

286


Introduction

The 98L Series are direct-operated backpressure/relief valves that are used in a variety of liquid or gas applications, such as pump recirculation, general backpressure, and relief applications. The Type 98LD uses additional pressure loading to maintain relief differential pressures or backpressures.

1. For inlet pressure in excess of 1000 psig (69,0 bar) refer to the maximum disk pressure rating in Table 8. 2. For pressure settings under 10 psig (0,7 bar), inlet pressure should be limited to approximately 100 psig (6,9 bar) so the setpoint adjustment can be obtained. 3. The unbalance forces change from the wide-open monitor mode to an active regulator mode such that the Type 627M or 627MH should have a 3/8-inch (9,5 mm) or larger orifice when used as a wide-open monitor.

Regulator Tips

Use control lines of equal size or greater than the control tap size on the regulator as supplied by the manufacturer. If a long control line is required, make it bigger. A rule of thumb is go to the next nominal pipe size every 20 feet (6,1 meters) of control line. Small control lines cause a delayed response of the regulator, leading to increased chance of instability. A 3/8-inch (9,5 mm) OD tubing is the minimum recommended control line size.

Introduction

The Types 1098-EGR and 1098H-EGR regulators provide economical and accurate pressure control in a wide variety of applications. The Type 1098H-EGR is used for higher outlet pressure settings.

The superior performance of this regulator is due to the amplifying effect of the pilot and the two-path control system. Changes in outlet pressure act quickly on the actuator diaphragm to provide fast response to changes. The pilot amplifies system changes positioning the main valve for precise control.

1. For other combinations, multiply table values by 1.6 for a size 30 actuator, 0.4 for a size 70 actuator, 2.0 for a low-gain Type 6352 or 6353 pilot restriction, and 0.5 for a high-gain Type 6352 or 6353 pilot restriction. For instance, a standard 2-inch (DN 50) Type 1098-EGR-6352 regulator with black pilot control spring and blue main valve spring has a proportional band of 0.3 psi (21 mbar) as given in the table, but this same regulator with low-gain restriction and size 70 actuator has a proportional band of 0.3 psi (21 mbar) x 2.0 x 0.4 = 0.24 psi (17 mbar).

Four easy ways to find the products you need . . .

1. Section headers at the top of each page are grouped by application of product (i.e., Air, Process Gases, etc.).2. The Product Index at the back of this Application Guide contains a detailed list of products arranged by type and application.3. If you know the application and product number, turn to the Application Map of that section and locate the Section Outline which indexes all of the products found in that section.4. Look for the product type number in the Quick Reference Chart in the Table of Contents.

1. For other restrictions, multiply table values by 2.0 for a low-gain restriction or by 0.5 for a high gain restriction. For instance, a standard 2-inch (DN 50) Type 1098H-EGR-6354L regulator with blue control spring and blue main valve spring has a proportional band of 2.0 psi (0,14 bar) as given in the table, but this same regulator with low-gain restriction has a proportional band of 2.0 psi (138 mbar) x 2.0 = 4.0 psi (276 mbar).

Regulator Tip

For every 15 psi (1,0 bar, differential) pressure differential across the regulator, expect approximately a 1°F (-17°C) drop in gas temperature due to the natural refrigeration effect. Freezing is often a problem when the ambient temperature is between 30° and 45°F (-1° and 7°C).

Introduction

The Y690VB Series vacuum breakers are used in applications where an increase in vacuum must be limited. When there is an increase in vacuum (decrease in pressure) beyond the setpoint on the diaphragm, it moves the disk away from the seat. This permits atmosphere or a positive pressure to enter the system and restore the controlled vacuum to its original vacuum pressure setting.

The Type Y690VBM has a control line connection and O-ring stem seal for external pressure registration.

Introduction

The Type Y692 is a direct-operated regulator used for accurate pressure control on very low-pressure blanketing systems. Downstream pressure is sensed through a pitot tube installed in the lower casing of the regulator, thus no external control line is required.

Introduction

The Y692VB Series vacuum breakers areused in applications where an increase in vacuum must be limited. An increase in vacuum (decrease in absolute pressure) beyond a certain value registers on the diaphragm of the Y692VB Series, moving the disk away from the seat. This permits atmosphere or a positive pressure to enter the system and restore the controlled vacuum to its original pressure setting. The Type Y692VBM has a control lineconnection and O-ring stem seal to blockthe throat for external pressure registration.

Introduction

The Type Y695A backpressure/relief valves are direct-operated and are used to maintain a constant inlet pressure or vessel pressure with the outlet flowing to atmosphere or to a system whose pressure is lower than the inlet.

The Type Y695AM has a blocked throat and O-ring stem seal to allow for external pressure registration. The lower diaphragm case is tapped 1/2-inch threaded NPT for control line connection.

Introduction

The Y695VR Series vacuum regulators are used where a decrease in vacuum must be limited. A decrease in vacuum (increase in absolute pressure) on the diaphragm moves the disk away from the seat, allowing a higher vacuum source to return the system to the setpoint.

The Type Y695VRM has a control line connection and blocked throat for external pressure registration.

Figure 2. Type Y696VR Operational Schematic

Introduction

The Y696VR Series vacuum regulators are used where a decrease in vacuum must be limited, such as between a tank and vacuum source to control vacuum in tank. A decrease in vacuum (increase in absolute pressure) on the diaphragm moves the disk away from the seat, allowing a higher vacuum source to return the system to the setpoint.

The Type Y696VRM has a control line connection and blocked throat for external pressure registration.
