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 11 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 valve is assigned a serial number which can be found on the valve body. 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 Emerson sales office
or Local Business Partner for technical assistance. When ordering
replacement parts, refer to the serial number and to the 11‐character part number for each part required from the
following parts list.
