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. .
