3 Inlet valve
3.1 Description
Refer to Figure 24. The inlet valve is a pneumatically operated butterfly valve which isolates the GXS dry vacuum
pumping system from the upstream process.
The valve seat design provides complete isolation of flowing media from the body and stem by a totally encasing
design. Inlet valves are pneumatically operated single acting with a spring return and a 24 V d.c operating solenoid.
In the event of a power failure, the valve will close automatically.
Note: An ISO - ANSI inlet spool is required to fit an Inlet valve to the GXS dry vacuum pumping system.
Figure 24 - Inlet valve
These inlet valves are designed for VACUUM use only, do not pressurise.
Complete the mechanical installation before any electrical or pneumatic connections are made.
Leak test the system after installation and seal any leaks found to prevent leakage of dangerous
substances out of the system and leakage of air into the system.
Can cause muscle strain or back injury. Use lifting aids and proper lifting techniques when
removing or replacing the inlet valve.
Refer to Section 3.3 for weight information.
