Catalyst Auto Valve Assembly
– CAV:
CAV Servicing notes:
The catalyst auto valve needs little servicing as all components are suitable for both
MEKP and recommended AAP catalysts
The movement of the spool as indicated from the aluminum air cylinder end should be
between 4 and 5 mm. Any less or greater can cause Catalyst to flow incorrectly so
ensure this movement is observed to be correct by measurement using calipers after
service and before using the machine in production.
Take care not to damage or scratch the Spool Internal Body (6369) when O-ring (3316)
needs replacing.
The valve should only need servicing if air or catalyst is noted to weep from between the
Air Cylinder (6078) and Stainless Steel Body (6067). In this case the O-ring (3316)
should be renewed.
If catalyst appears to weep back to the catalyst bottle during injection mode then the
internal Spool O-rings (6004) need replacing.
If catalyst is observed to weep from the Injection Nozzle during recirculation mode then
the small front O-ring (6079) needs replacing.
