Instruction Manual EZ Valve D100401X012 June 2014 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. Figure 2.
EZ Valve Instruction Manual June 2014 D100401X012 4. With a leak-off bonnet construction, remove the pipe plugs (key 14) 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. 5. 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.
Instruction Manual EZ Valve D100401X012 June 2014 Note If the valve has ENVIRO-SEAL or HIGH-SEAL live-loaded packing installed, refer to instruction manuals ENVIRO-SEAL Packing System for Sliding Stem Valves, D101642X012, or HIGH-SEAL Live Loaded Packing System, D101453X012, for packing instructions. Figure 6 shows a typical HIGH-SEAL packing system. Figures 7 and 8 show typical ENVIRO-SEAL systems. Figure 3.
Instruction Manual EZ Valve D100401X012 June 2014 Packing Lubrication Note ENVIRO-SEAL or HIGH-SEAL packing does not require lubrication. If an optional lubricator or lubricator/isolating valve (figure 2) is provided for PTFE/composition or other packings that require lubrication, it will be installed in an optional tapped hole in the bonnet. Use a good quality silicon-base lubricant. Packing used in oxygen service or in processes with temperatures over 260_C (500_F) should not be lubricated.
Instruction Manual EZ Valve D100401X012 June 2014 If the packing is relatively new and tight on the stem, and if tightening the packing flange nuts does not stop the leakage, the valve stem may be worn or nicked so that a seal cannot be made. The surface finish of a valve stem is critical for making a good packing seal. If the leakage comes from the outside diameter of the packing, the leakage may be caused by nicks or scratches around the packing box wall.

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. 4. Loosen the packing flange nuts (key 5, figure 11) so that the packing is not tight on the valve stem.
Instruction Manual D100401X012 EZ Valve June 2014 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 Process Management representative immediately if a discrepancy between actual parts and approved parts is suspected. 11.

Instruction Manual EZ Valve D100401X012 June 2014 1. Lift the valve plug and stem assembly [or the plug guide, disk retainer, and disk (keys 27, 28, and 29, figure 13) if used], out of the valve body and set it on a protective surface.
Instruction Manual EZ Valve D100401X012 June 2014 The seating surfaces of the valve plug post and seat ring must be free from nicks, scratches, or any other damage which could affect the proper shutoff. Replace or repair trim parts as appropriate. Note If the soft seat disk is damaged, the entire plug assembly must be replaced. Valves with ENVIRO-SEAL Bellows Seal Bonnets Perform the following steps to remove the valve trim. 1.
Instruction Manual D100401X012 EZ Valve June 2014 5. Remove the stem/bellows assembly from the soft-jaw chuck or vise. Place a wrench on the flat areas on the valve stem just below the threads for the actuator/stem connection to keep the stem from turning. Then, unscrew the adaptor (key 24, figure 11), which also includes the valve plug (key 2) or valve plug guide (key 27, figure 13), from the stem/bellows assembly (key 20, figure 11). 6.
EZ Valve June 2014 Instruction Manual D100401X012 Valves with Plain or Extension Bonnets Perform the following steps to assemble and install the trim. CAUTION To avoid weakening the stem that may cause failure in service, never reuse an old stem with a new valve plug. Using an old stem with a new plug requires drilling a new pin hole in the stem,which will weaken the stem. However, a used valve plug may be reused with a new stem. 1.
Instruction Manual D100401X012 EZ Valve June 2014 reused with a new stem except for valves with 0.5 through 1-inch ports and composition seats (see to figure 13). For these constructions, a used valve plug guide should only be used if the tip is reused. 3. For all valves with composition seats, screw the valve stem (key 7) into the valve plug guide (key 27, figure 13). Tighten to the torque value given in figure 10. Refer to figure 10 to select the proper drill size.
EZ Valve June 2014 Instruction Manual D100401X012 4. Place the spiral wound gasket, shim, and bonnet gasket (keys 12, 25, 10) on the shoulder of the seat ring retainer. 5. Mount the bonnet on the valve body and complete the assembly according to steps 10 through 15 of the Replacing Packing procedure, omitting steps 12 and 13 if new packing is not being installed. Be sure to observe the note prior to step 11.
Instruction Manual D100401X012 EZ Valve June 2014 2. Thread the valve plug (key 2) or, the valve plug guide (key 27, figure 13) if the valve has composition seats, onto the adaptor (key 24, figure 11). Tighten to the torque valve given in figure 10. Note Valve plugs may not be pre-drilled. Follow the procedure in the following step. 3. If the valve plug is not pre-drilled, drill a hole according to figure 10.
EZ Valve June 2014 Instruction Manual D100401X012 d. Install the seat ring retainer and bushing assembly on the top of the seat ring, ensuring that the seat ring retainer slips onto the seat ring properly. Any rotation orientation of the seat ring retainer with respect to the valve body is acceptable. e. Place the spiral wound gasket, shim, and bonnet gasket (keys 12, 25, and 10) on the shoulder of the seat ring retainer. f.
Instruction Manual EZ Valve D100401X012 June 2014 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. Note The ENVIRO-SEAL stem/bellows assembly has a one-piece stem. Table 4.
EZ Valve Instruction Manual June 2014 D100401X012 finger-tight. Then, tighten the adaptor with a wrench until the valve stem hole lines up with the next adaptor pin hole. Drive in a new pin (key 36, figure 11) to lock the assembly. Make certain the spiral wound gasket, shim, and bonnet gasket (keys 12, 25, and 10, figure 12) are located on the shoulder of the seat ring retainer. 10. Inspect the seat ring. Replace, if necessary. 11.
Instruction Manual D100401X012 EZ Valve June 2014 2. Using care, remove the valve plug and stem assembly, and, if necessary, the seat ring retainer and bushing assembly from the valve body. Remove and discard the existing bonnet gasket (key 10, figure 12) and gasket (key 22, figure 11). Cover the valve body opening to protect sealing surfaces and to prevent foreign material from entering the valve body cavity.
Instruction Manual EZ Valve D100401X012 June 2014 1. Remove the two diametrically opposed pipe plugs (key 16). 2. Connect a purging fluid to one of the pipe plug connections. 3. Install appropriate piping or tubing in the other pipe plug connection to pipe away the purging fluid or to make a connection to an analyzer for leak testing. 4. When purging or leak testing has been completed, remove the piping or tubing and reinstall the pipe plugs (key 16).
