Catalyst Auto Valve Assembly
– CAV
(see figure 16 & 17)
CAV Servicing Notes: (see figure 16 & 17)
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 aluminium 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 callipers 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.
