Catalyst Overpressure Valve (Polyester option only)
See drawing 22021
Under normal operational circumstances the catalyst overpressure valve is
maintenance free.
If catalyst leaks constantly from fitting (4), O rings (2) must be replaced
Important Note: It is essential that the internal spring tension is not disturbed in the event
of servicing this unit.
Procedure
To renew front O rings
1. Disconnect red signal pipe and clear overflow pipe. Unscrew whole assembly from catalyst
pump using 19 AF spanner on the forward stainless steel body taking care of any small
residual pressurised catalyst as thread seal is broken. DO NOT disturb the spring tension
end cap (0671).
2. Hold brass body (1035) and unscrew stainless steel body (1032). Pull shaft (1034), and
collar (1033) from body, replace O rings (0750) and reassemble. Ensure shaft is reinserted
with rounded end into the body.
3. Reassemble observing order illustrated in dwg. 22021. Ensure bodies (1032) and (1035)
are correctly screwed together using PTFE tape or similar thread sealant.
4. Reattach valve to catalyst pump using thread sealant.
