Some of the specifications for a given valve assembly appear on the actuator nameplate if the valve is part of a control valve assembly. Installation WARNING Personal injury or equipment damage caused by 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 overpressure protection as required by accepted industry or local, state, and federal codes and good engineering practices. CAUTION When ordered, the valve configuration and construction materials were selected to meet particular pressure, temperature, pressure drop, and controlled fluid conditions. Since some 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 Fisher Controls sales office or sales representative. 1. Before installing the valve, inspect it to be certain that the valve body cavity is free of foreign material. Clean out all pipelines to remove scale, welding slag, and other foreign materials. 2. 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 body. With some valves, the actuator may also need to be supported when it is not vertical. For more information, consult your Fisher Controls sales office or sales representative. Flow through the valve must be in the direction indicated by the arrow on the valve body. 3. Use accepted piping practices when installing the valve in the pipeline. Use a suitable gasket between the valve body and pipeline flanges. 4. With a leak-off bonnet construction, remove the pipe plug to hook up the leak-off piping. 5. 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 appropriate actuator instruction manual for the actuator mounting procedure. 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. Refer to table 3 for packing torques. 3

Torques are for standard packing only. Refer to the appropriate instruction manual for packing nut tightening requirements for ENVIRO-SEAL packing. Valves with ENVIRO-SEAL packing will not require this initial re-adjustment. See your Fisher Controls instruction manual titled ENVIRO-SEAL Packing System for Sliding-Stem Valves for packing instructions. If you wish to convert your present packing arrangement to ENVIRO-SEAL packing, refer to the retrofit kits listed in the parts kit subsection near the end of this manual. Maintenance WARNING Avoid personal injury or property damage from sudden release of process pressure or bursting of parts. Before performing any maintenance operations: 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. Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure from both sides of the valve. Drain the process media from both sides of the valve. Vent the power actuator loading pressure and relieve any actuator spring precompression. Use lock-out procedures to be sure that the above measures stay in effect while you work on the equipment. Due to the care Fisher Controls takes in meeting all manufacturing requirements (heat treating, dimensional tolerances, etc.), use only replacement parts manufactured or furnished by Fisher Controls. 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 these maintenance operations may be performed with the valve in the line. 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 will not seal properly. If the valve has ENVIRO-SEAL packing installed, refer to instruction manual titled ENVIRO-SEAL Packing System for Sliding-Stem Valves, Form 5306, for packing instructions. Figure 3 in this manual shows typical ENVIRO-SEAL packing systems. Packing Maintenance WARNING On a valve equipped with an ENVIRO-SEAL bellows seal bonnet, packing leakage may be an indication of a broken or failed bellows seal, which could result in personal injury. On a valve equipped with an ENVIRO-SEAL bellows seal bonnet, packing is a secondary seal in case the bellows seal fails. Packing leakage may be an indication of a broken or failed bellows seal. First, tighten the packing per instructions in the Tightening Packing section. Then, if leaking persists, check the ENVIRO-SEAL bellows seal for failure. 4

44B1188-A / DOC Figure 2. Standard Packing Arrangements 44B1188-A / DOC Tightening Packing 1. Tighten the packing flange nuts as described for the appropriate packing: a. 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. b. For PTFE packing, 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 nuts until the packing flange is level and at a 90-degree angle to the valve stem. c. For ENVIRO-SEAL packing, refer to instruction manual titled ENVIRO-SEAL Packing System for Sliding-Stem Valves, Form 5306, for packing instructions. Figure 3.

The sudden release of stored energy can cause uncontrolled movement of the bonnet. 1. Isolate the control valve from the line pressure, release pressure from both sides of the valve body, and drain the process media from both sides of the valve. Disconnect any leak-off piping from the bonnet. If using a power actuator, also shut off all pressure lines to the power actuator, release all pressure from the actuator. Use lock-out procedures to be sure that the above measures stay in effect while you work on the equipment. 2. Disconnect the stem connector, and then remove the actuator from the valve by unscrewing the yoke locknut (key 18). The following step provides assurance that fluid pressure in the packing box has been relieved. 3. Loosen, but do not remove, the packing flange nuts (key 212) so that the packing is not tight on the valve stem. Remove any travel indicator parts and stem locknuts from the valve stem threads. The following step provides additional assurance that the valve body fluid pressure has been relieved. 4. Hex nuts (key 11) attach the bonnet to the valve. Loosen these nuts approximately 1/8 inch (3 mm). Then loosen the body-to-bonnet gasketed joint by either rocking the bonnet or prying between the bonnet and valve. 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 and valve plug stem assembly (keys 12 and 7) as a unit. If the valve plug stem assembly does not come out of the valve with the bonnet, pull it out of the valve body. Set the bonnet and valve plug assembly on a protective surface, to prevent damage to the bonnet gasket surface. 5. Remove the valve plug and stem from the bonnet, and carefully set it on a protective surface. 6. Remove and discard the existing bonnet gasket (key 9, figure 5). CAUTION When installing a valve plug on the ENVIRO-SEAL stem/bellows assembly, the valve stem must not be rotated. Damage to the bellows may result. Do not grip the bellows shroud or other parts of the stem/bellows assembly. Grip only the flat areas on the stem where it extends out of the top of the bellows shroud. 7. To attach the valve plug (key 7) to the stem of the new ENVIRO-SEAL stem/bellows assembly (key 20), place the valve plug in a soft-jaw chuck or other type of vise. Do not grip the plug on any seating surface. Position the plug in the chuck or vise for easy threading of the stem extending out of the bellows shroud. Thread the stem into the valve plug. Tighten by gripping the flats of the stem extending out of the top of the bellows shroud with a wrench. Do not grip the bellows shroud or other areas of the stem/bellows assembly. Turn the stem/bellows assembly until the hole in the plug aligns with the hole in the stem. Secure the valve plug to the stem with a new pin (key 22). 8. Inspect the valve seat ring (key 2, figure 5) and seat ring retainer (key 3, figure 5). Replace, if necessary. 9. Place a new bonnet gasket (key 9) into the valve body in place of the bonnet gasket. Install the stem/ bellows assembly by placing it into the valve body on top of the bellows gasket. 10. Place a new upper bonnet gasket (key 9) over the stem /bellows assembly. Place the new ENVIRO-SEAL bellows seal bonnet (key 12) over the stem/bellows assembly. 6
