Purging The Enviro-Seal Bellows Seal Bonnet; Parts Ordering; Parts Kits - Fisher EAS easy-e Instruction Manual

Instruction Manual
D100397X012
Note
The ENVIRO‐SEAL stem/bellows assembly has a one‐piece stem.
4. To remove the existing valve plug from the stem, first, place the existing plug stem assembly and valve plug in a
soft‐jaw chuck or other type of vise so that the jaws grip a portion of the valve plug that is not a seating surface.
Drive out or drill out the pin.
5. Then, reverse the plug stem assembly in the soft‐jaw chuck or vise. Grip the flat areas on the valve stem just below
the threads for the actuator/stem connection. Unscrew the existing plug from the valve stem.
6. To attach either the existing valve plug or a new one to the stem of the new ENVIRO‐SEAL stem/bellows assembly, it
is necessary to first attach the plug to the adaptor. Locate the adaptor. Notice that a hole has not been drilled in the
threads where the plug screws onto the adaptor. Secure 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 adaptor.
Thread the adaptor into the valve plug and tighten to the appropriate torque value.
7. Complete the installation by following steps 7 through 9 and steps 12 through 15 of the ENVIRO‐SEAL Bellows Seal
and Bonnet installation instructions given above.
Purging the ENVIRO‐SEAL Bellows Seal Bonnet
The ENVIRO‐SEAL bellows seal bonnet has been designed so that it can be purged or leak tested. Refer to figure 8 for
an illustration of an ENVIRO‐SEAL bellows seal bonnet, and perform the following steps for purging or leak testing.
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).

Parts Ordering

Each body‐bonnet assembly is assigned a serial number which can be found on the valve. This same number also
appears on the actuator nameplate when the valve is shipped from the factory as part of a control valve assembly.
Refer to the serial number when contacting your
assistance. When ordering replacement parts, refer to the serial number and to the eleven‐character part number for
each part required from the following parts kit or parts list information.
Refer to table 6 for standard and common material designations.
WARNING
Use only genuine Fisher replacement parts. Components that are not supplied by Emerson Automation Solutions should
not, under any circumstances, be used in any Fisher valve, because they may void your warranty, might adversely affect the
performance of the valve, and could cause personal injury and property damage.
