Description
Fisher NPS 12 through 30 CL150 through CL600 ET/EWT and ED/EWD series control valves are used for either throttling or on/off control of a wide variety of liquids and gasses.
ET/EWT series valves utilize a hanging cage and a seat ring that is threaded into the cage. These valves have two spring loaded seal rings, one between the cage and plug and another between the seat ring and valve body, which provide up to a Class V standard shutoff. They are used for low to medium temperature applications between -46_C (-50_F) and 232_C (450_F). This temperature range can be extended to 316_C (600_F) for nonoxidizing service and to 260_C (500_F) for oxidizing service by using the High Temperature (HTS1) seal.
The temperature range of the ET/EWT series can be extended to cryogenic temperatures as low as -198_ (-325_F) with the ET-C and EWT-C specialized versions of these valves. The specialized valves feature unique trim, seals, and a longer extension bonnet to tolerate the extreme cold.
ED/EWD series valves utilize a hanging cage and a seat ring that is bolted into the body. These valves have two graphite piston rings between the cage and plug, which provide up to a Class IV standard shutoff. They are used for high temperature applications between 316_C (600_F) and 593_C (1100_F). Shutoff can be improved to Class V by using the Bore seal.
A range of severe service trims are available for noise abatement or cavitation control. Noise abatement trims help with aerodynamic noise attenuation in gas services and feature a Whisper Trim III or WhisperFlo cage. Cavitation control trims help prevent the damaging effects of liquid cavitation and include either a Cavitrol III cage (for services without entrained particulate) or Dirty Service Trim (DST) set (for services with entrained particulate).

Installation
WARNING
Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal injury.
Personal injury or equipment damage caused by the sudden release of pressure may result if the valve assembly is installed where service conditions could exceed the limits given in table 1 or on the appropriate nameplates. To avoid such injury or damage, provide a relief valve for over-pressure protection as required by government or accepted industry codes and good engineering practices.
Check with your process or safety engineer for any additional measures that must be taken to protect against process media.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this instruction manual.

CAUTION
When ordered, the valve configuration and construction materials were selected to meet particular pressure, temperature, pressure drop, and controlled fluid conditions. Responsibility for the safety of process media and compatibility of valve materials with process media rests solely with the purchaser and end-user. Since some valve body/trim material combinations are limited in their pressure drop and temperature ranges, do not apply any other conditions to the valve without first contacting your Emerson sales office
Before installing the valve, inspect the valve and pipelines for any damage and any foreign material which may cause product damage.
1. Before installing the valve, inspect the valve and associated equipment for any damage and any foreign material.
2. Make certain that the valve body interior is clean, that pipelines are free of foreign material, and the valve is
oriented so that pipeline flow is in the same direction as the arrow on the side of the valve.
3. The control valve assembly may be installed in any orientation unless limited by seismic criteria. However, the
normal method is with the actuator vertical above the valve. Other positions may result in uneven valve plug and cage wear and improper operation. Support the actuator if it is not installed in the vertical position. For more information, consult your Emerson sales office or Local Business Partner.
4. Use accepted piping and welding practices when installing the valve in the line. For flanged valves, use a suitable
gasket between the valve and pipeline flanges.
or Local Business Partner.
CAUTION
Depending on valve body materials used, post weld heat treating may be required. If so, damage to internal elastomeric and plastic parts, as well as internal metal parts is possible. In general, if post weld heat treating is to be performed, all trim parts should be removed. Contact your Emerson sales office or Local Business Partner for additional information.
5. With a leak‐off bonnet construction, remove the pipe plugs (key 46) to hook up the leak-off piping. If continuous
operation is required during inspection or maintenance, install a three‐valve bypass around the control valve assembly.
6. If the actuator and valve are shipped separately, refer to the actuator mounting procedure in the appropriate
actuator instruction manual.
WARNING
Personal injury could result from packing leakage. Valve packing was tightened before shipment; however the packing might require some readjustment to meet specific service conditions. Check with your process or safety engineer for any additional measures that must be taken to protect against process media.
Valves with ENVIRO‐SEALt live‐loaded packing or HIGH‐SEAL ULF live‐loaded packing will not require this initial readjustment. See the Fisher instruction manuals titled ENVIRO‐SEAL Packing System for Sliding‐Stem Valves (D101642X012 instructions. If you wish to convert your present packing arrangement to ENVIRO-SEAL packing, refer to the retrofit kits listed in the Parts Kits section.

Instruction Manual
D103553X012
Valve parts are subject to normal wear and must be inspected and replaced as necessary. Inspection and maintenance frequency depends on the severity of service conditions. This section includes instructions for packing lubrication, packing maintenance, and trim maintenance. All maintenance operations may be performed with the valve in the line.
WARNING
Avoid personal injury or property damage from sudden release of process pressure or bursting of parts. Before performing any maintenance operations:
D Do not remove the actuator from the valve while the valve is still pressurized.
D Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal
injury.
D Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the
actuator cannot suddenly open or close the valve.
D Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure
on both sides of the valve. Drain the process media from both sides of the valve.
D Vent the pneumatic actuator loading pressure and relieve any actuator spring precompression.
D Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.
D The valve packing box may contain process fluids that are pressurized, even when the valve has been removed from the
pipeline. Process fluids may spray out under pressure when removing the packing hardware or packing rings, or when loosening the packing box pipe plug.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
Note
Whenever a gasket seal is disturbed by removing or shifting gasketed parts, a new gasket should be installed upon reassembly. This is necessary to ensure a good gasket seal because the used gasket might not seal properly.
Packing Lubrication
Note
ENVIRO-SEAL and HIGH-SEAL packing do not require lubrication.
WARNING
To avoid personal injury or property damage resulting from fire or explosion, do not lubricate packing used in oxygen service or in processes with temperatures over 260_C (500_F).
If a lubricator or lubricator/isolating valve is provided for PTFE/composition or other packings that require lubrication, it will be installed in place of the pipe plug (key 46). Use a good quality silicon‐base lubricant. To operate the lubricator, simply turn the cap screw clockwise to force the lubricant into the packing box. The lubricator/isolating valve operates the same way except open the isolating valve before turning the cap screw and then close the isolating valve after lubrication is completed.

Packing Maintenance
Note
For valves with ENVIRO-SEAL packing, see the Fisher instruction manual, ENVIRO-SEAL Packing System for Sliding-Stem Valves,
D101642X012
For valves with HIGH-SEAL packing, see the Fisher instruction manual, HIGH-SEAL ULF Live-Loaded Packing System,
D101453X012
For spring‐loaded single PTFE V‐ring packing, the spring (key 8, figure 2) maintains a sealing force on the packing. If leakage is noted around the packing follower (key 13, figure 2), check to be sure the shoulder on the packing follower is touching the bonnet (key 35). If the shoulder is not touching the bonnet, tighten the packing flange nuts (key 5) until the shoulder is against the bonnet. If leakage cannot be stopped in this manner, proceed to the Replacing Packing section.
If there is undesirable packing leakage with other than spring‐loaded packing, first try to limit the leakage and establish a stem seal by tightening the packing flange nuts.
If the packing is relatively new and tight on the valve stem (key 2B) and if tightening the packing flange nuts does not stop the leakage, it is possible that the valve stem is worn or nicked so that a seal cannot be made. The surface finish of a new valve stem is critical for making a good packing seal. If the leakage comes from the outside diameter of the packing, it is possible that the leakage is caused by nicks or scratches around the packing box wall. If performing any of the following procedures, inspect the valve stem and packing box wall for nicks and scratches.

, for packing instructions.
Replacing Packing
1. Isolate the control valve from the line pressure, release pressure from both sides of the valve, and drain the process
media from both sides of the valve. If using a power actuator, also shut off all pressure lines to the power actuator, release all pressure from the actuator, and use lock‐out procedures to prevent injury while you work on the equipment.
2. Remove the actuator from the valve body by following the appropriate Actuator Removal procedure from the
actuator instruction manual.
3. Loosen the packing flange nuts (key 5) so that the packing is not tight on the valve stem (key 2B). Remove any
travel indicator parts and locknuts from the valve stem threads.
WARNING
To avoid personal injury or property damage caused by uncontrolled movement of the bonnet, loosen the bonnet by following the instructions in the next step. Do not remove a stuck bonnet by pulling on it with equipment that can stretch or store energy in any other manner. The sudden release of stored energy can cause uncontrolled movement of the bonnet.
CAUTION
Avoid damage to the seating surfaces caused by the valve plug and stem assembly dropping from the bonnet after being lifted part way out. When lifting the bonnet, temporarily install a locknut on the valve stem. This locknut will prevent the valve plug and stem assembly (key 2) from dropping out of the bonnet.
If the cage (key 3) starts to lift with the bonnet, tap it with a plastic mallet, or other soft material, to be sure it stays in the valve body.
Note
The following step also provides additional assurance that the valve body fluid pressure has been relieved.

D103553X012
4. Hex nuts (key 16) attach the bonnet (key 35) to the valve body. Loosen these nuts or cap screws approximately 3
mm (1/8 inch). Then loosen the body‐to‐bonnet gasketed joint by either rocking the bonnet or prying between the bonnet and valve body. Work the prying tool around the bonnet until the bonnet loosens. If no fluid leaks from the joint, remove the nuts completely and carefully lift the bonnet.
5. Remove the locknut from the valve stem and separate the valve plug and stem assembly from the bonnet. Set the
parts on a protective surface to prevent damage to gasket or seating surfaces.
6. Remove the bonnet gasket (key 11) and cover the opening in the valve to protect the gasket surface and prevent
foreign material from getting into the valve body cavity.
CAUTION
To prevent possible product damage, cover the opening in the valve in the following procedure to prevent foreign material from getting into the valve body cavity.
7. Remove the packing flange nuts (key 5), packing flange (key 37), upper wiper (key 12, figure 2), and packing
follower (key 13, figure 2). Carefully push out all the remaining packing parts from the valve side of the bonnet using a rounded rod or other tool that will not scratch the packing box wall. Clean the packing box and the metal packing parts.
8. Inspect the valve stem threads and packing box surfaces for any sharp edges that might cut the packing. Scratches
or burrs could cause packing box leakage or damage to the new packing. If the surface condition cannot be improved by light sanding, replace the damaged parts by following the appropriate steps in the Trim Maintenance section.
9. Remove the cover protecting the valve body cavity.
10. Install a new bonnet gasket (key 11), making sure the gasket seating surfaces are clean and smooth. Place the valve plug and stem assembly into the valve body, making sure it is properly centered on the seat ring (key 9). Also make sure the valve plug (key 2A) sealing parts are evenly engaged by the chamfer in the top inside diameter of the cage (key 3) to avoid damaging the parts. Then slide the bonnet over the valve stem (key 2B) and onto the studs (key 15).
Note
Proper performance of the bolting procedures in step 11 compresses the bonnet and cage gaskets (key 11) enough to seal the body-to-bonnet joint.
The proper bolting procedures in step 11 include--but are not limited to--ensuring that bolting threads are clean and evenly tightening the hex nuts onto the studs in a crisscross pattern. Tightening one nut may loosen an adjacent nut. Repeat the crisscross tightening pattern several times until each nut is tight and the body-to-bonnet seal is made.
Studs and hex nuts should be installed such that the manufacturer’s trademark and material grade marking is visible, allowing easy comparison to the materials selected and documented in the Emerson/Fisher serial card provided with this product.
WARNING
Personal injury or damage to equipment could occur if improper stud and nut materials or parts are used. Do not operate or assemble this product with stud(s) and nut(s) that are not approved by Emerson/Fisher engineering and/or listed on the serial card provided with this product. Use of unapproved materials and parts could lead to stresses exceeding the design or code limits intended for this particular service. Install studs with the material grade and manufacturer's identification mark visible. Contact your Emerson sales office approved parts is suspected.

11. Lubricate the studs (key 15) and install hex nuts (key 16), using accepted bolting procedures during tightening, so that the body-to-bonnet joint will withstand test pressures and application service conditions. Use the bolt torques in table 4 as guidelines.
12. Install new packing and the metal packing box parts according to the appropriate arrangement in figure 2. Place a smooth‐edged pipe over the valve stem, and gently tap each soft packing part into the packing box one piece at a time, being sure that air is not trapped between adjacent soft parts.
13. Slide the packing follower (key 13, figure 2), upper wiper (key 12, figure 2), and packing flange (key 37) into position. Lubricate the packing flange studs (key 4) and the faces of the packing flange nuts (key 5). Replace the packing flange nuts.
14. For spring‐loaded PTFE V‐ring packing, tighten the packing flange nuts until the shoulder on the packing follower (key 13, figure 2) contacts the bonnet.
For graphite packing, tighten the packing flange nuts to the maximum recommended torque shown in table 3. Then, loosen the packing flange nuts and retighten them to the recommended minimum torque shown in table 3.
For other packing types, tighten the packing flange nuts alternately in small, equal increments until one of the nuts reaches the minimum recommended torque shown in table 3. Then, tighten the remaining flange nut until the packing flange (key 3, figure 2) is at a 90‐degree angle to the valve stem.
15. Mount the actuator on the valve assembly, and reconnect the actuator and valve stem according to the procedure in the appropriate actuator instruction manual.

Trim Maintenance
WARNING
Refer to the WARNING at the beginning of the Maintenance section in this instruction manual.
Disassembly
1. Complete steps 1 through 5 of the Replace Packing section to remove the actuator, bonnet, and plug and stem from the valve body. Remove the bonnet gasket (key 11).
WARNING
To avoid personal injury due to leaking fluid, avoid damaging gasket sealing surfaces. The surface finish of the valve stem (key 2B) is critical for making a good packing seal. The inside surface of the cage (key 3) is critical for smooth operation of the valve plug. The seating surfaces of the valve plug (key 2A) and seat ring (key 9) are critical for proper shutoff. Unless inspection reveals otherwise, assume all these parts are in good condition and protect them accordingly.
2. Packing parts can be removed if desired. Replace these parts as described in the Replace Packing section.
3. Install 3/8”-16 UNC-2A eye bolts with a minimum threaded length of 13 mm (0.5 inches) into the tapped holes in the top of the cage (key 3) and carefully lift it out of the valve body. For ET/EWT valves, the seat ring (key 9) will be removed with the cage as an assembly due to the seat ring being screwed into the bottom of the cage and secured with tack welds. If the cage is stuck in the valve, use a rubber mallet to strike the exposed portion of the cage at several points around its circumference. Set the part(s) on a protective surface to prevent damage to gasket or seating surfaces.
4. Remove the cage gasket (key 11).

For ED/EWD and ET-C/EWT-C Valves, using the below procedure, disassemble the seat ring from the valve body:
a. Unscrew the seat ring cap screws (key 49).
b. Install 3/8”-16 eye bolts with a minimum threaded length of 0.5 inches into the two equally spaced tapped holes
in the top of the seat ring (key 9).
c. Carefully lift the seat ring out of the valve body using the eye bolts as lifting points.
d. Set the seat ring on a protective surface.
e. Remove the seat ring gasket (key 13) from the valve body.
6. Cover the opening in the valve to protect the gasket surface and prevent foreign material from getting into the valve body cavity. Inspect parts for wear and damage which would prevent proper operation of the valve. If the cage requires replacement take note that for ET/EWT valves a replacement is available individually (key 3 only) or as a cage and seat ring assembly (key 3 and 9). The valve plug and seat ring, along with their respective sealing parts, will be inspected in the Valve Plug and Seat Ring maintenance procedures.
Valve Plug Maintenance
With the valve plug and stem assembly (key 2) removed according to the Disassembly procedure, proceed as appropriate:
CAUTION
Be careful not to scratch the surfaces of the seal ring grooves in the valve plug (key 2A) or any surfaces of the replacement parts.
For ET/EWT Valves
1. Carefully pry or cut out the plug seal ring (key 28) from its groove in the valve plug (key 2A). Discard the old plug seal ring.
2. Inspect the valve plug (key 2A) and stem (key 2B) for nicks, scratches, or other damage that would prevent proper operation of the valve. If replacement of either is necessary, replace as a complete valve plug and stem assembly (key 2).
CAUTION
To avoid damaging the seal ring, slowly and gently stretch it for the following procedure. Avoid jerking sharply on the ring.
3. Install the replacement plug seal ring (key 28) with the open side facing the top or bottom of the valve plug, depending on flow direction. The open side of the seal ring should face up (toward the actuator) in flow-up installations and down in flow-down installations.
To install the seal ring on the valve plug, first lubricate it with a general purpose silicone-base lubricant. Then gently stretch the seal ring and work it over the top edge of the valve plug. The PTFE material in the seal ring must be permitted time to cold-flow during the stretching procedure, so avoid jerking sharply on the ring. Stretching the seal ring over the valve plug may make it seem unduly loose when in the groove, but it will contract to its original size after insertion into the cage.

14. Each new piston ring (key 6) is furnished as a complete ring, and each must be broken into two approximately equal portions. Do this by placing the ring on edge on a smooth, hard surface and striking the ring squarely with a hammer.
15. Install the piston ring into the groove in the retainer (key 2C). Be sure to match the broken ends when installing the ring sections in the groove.
CAUTION
To avoid excessive leakage and seat erosion, the valve plug must be initially seated with sufficient force to overcome the resistance of the Bore Seal and contact the seat ring. You can correctly seat the valve plug by using the same force calculated for full load when sizing your actuator. With no pressure drop across the valve, this force will adequately drive the valve plug to the seat ring, thus giving the Bore Seal a predetermined permanent set.
With full actuator force applied and the valve plug fully seated, align the actuator travel indicator scale with the lower end of valve travel. Refer to the appropriate actuator instruction manual for information on this procedure.
Seat Ring Maintenance
With the seat ring (key 9) removed, according to the Disassembly procedure, proceed as appropriate:
CAUTION
Be careful not to scratch the surfaces of the seating surface or groove in the seat ring or the surfaces of the replacement parts.

Bore Seal Retrofit
Note
Additional actuator thrust is required for a valve equipped with the bore seal. When installing the bore seal in an existing valve, contact your Emerson sales office
or Local Business Partner for assistance in determining new actuator thrust requirements.
The bore seal retrofit will require a new valve plug and stem assembly (key 2), bore seal (key 64), and piston ring (key 6). The following steps will guide you in the assembly of these parts. Final installation into the valve body will be per the Assembly procedure.
CAUTION
To avoid leakage when the valve is returned to service, use appropriate methods and materials to protect all sealing surfaces of the new trim parts while assembling the individual parts and during installation in the valve body.
1. Apply a suitable high-temperature lubricant to the inside diameter of the bore seal. Also, lubricate the outside diameter of the valve plug where the bore seal must be pressed into the proper seating position (see figure 3).
2. Referring to figure 3, orient the bore seal for correct sealing action based on the process fluid flow direction through the valve.
D The open interior of the bore seal must face up in a valve with flow-up construction.
D The open interior of the bore seal must face down in a valve with flow-down construction.
3. Place the bore seal over the top of the valve plug. The retainer will help guide the bore seal down onto the valve plug. Do not force the bore seal over the plug. For flow-down constructions, skip to step 5.
4. An installation tool (see figure 4 and table 5) must be inserted into the bore seal prior to using the retainer to guide it down the valve plug.
5. Apply a suitable high-temperature lubricant to the threads on the valve plug. Then, place the retainer onto the valve plug and tighten the retainer using an appropriate tool such as a strap wrench. For flow-down constructions, skip to step 7.
6. Remove the retainer and then the installation tool. Place the retainer back onto the valve plug and tighten the retainer using an appropriate tool such as a strap wrench.
7. Using an appropriate tool such as a center punch, stake the threads on top of the valve plug in one place to secure the retainer (see figure 3).
8. Each new piston ring (key 6) is furnished as a complete ring, and each must be broken into two approximately equal portions. Do this by placing the ring on edge on a smooth, hard surface and striking the ring squarely with a hammer.
9. Install the piston ring into the groove in the retainer (key 2C). Be sure to match the broken ends when installing the ring sections in the groove.
CAUTION
To avoid excessive leakage and seat erosion, the valve plug must be initially seated with sufficient force to overcome the resistance of the Bore Seal and contact the seat ring. You can correctly seat the valve plug by using the same force calculated for full load when sizing your actuator. With no pressure drop across the valve, this force will adequately drive the valve plug to the seat ring, giving the Bore Seal a predetermined permanent set.

Assembly
After completing Packing Maintenance and/or Trim Maintenance procedures, the following steps will guide you through reassembly of the valve.
For ED/EWD and ET-C/EWT-C Valves only
1. Remove the cover protecting the valve body cavity.
2. Install a new seat ring gasket (key 13) into the valve body. Make sure the eye bolts that were installed in the seat ring (key 9) during the Disassembly procedure are still installed. Then using the eye bolts as lifting points, carefully lower the seat ring into the valve body. Make sure that the cap screw holes in the seat ring are lined up with their mating holes in the valve body. Remove the two eye bolts from the seat ring.
CAUTION
Uneven tightening of the cap screws (key 49) will result in the seat ring seating surface being askew from the valve plug seating surface, thereby preventing the valve from attaining its rated shutoff class. This is especially critical in ED/EWD valves equipped with the bore seal. If after assembly the rated shutoff class is not attained your Emerson sales office Local Business Partner can provide further assistance.
or
3. Secure the seat ring to the valve body using the cap screws (key 49). Tighten the cap screws in a criss-cross pattern working up to the final torque in four equal increments as specified in table 6.
4. Install a new cage gasket (key 11) into the valve body.
5. Make sure the eye bolts that were installed in the cage (key 3) or cage assembly during the Disassembly procedure are still installed. Then using the eye bolts as lifting points, carefully lower the cage into the valve body. Any rotational orientation of the cage with respect to the valve is acceptable.
6. Complete reassembly according to steps 10 through 15 of the Replace Packing section.
