Hello,
I purchased Coltri PMV (pressure maintaining valve) to my MCH6 compressor (same as on attached picture), but it doesn't work. It doesn't make back-pressure and that doesn't depend on position of adjustment screw. It always releases pressure from the beginning.
Is there somebody who has experience with this PMV?
I think that the bottom o-ring doesn't seal. Please, what is the size of this o-ring?
Thanks
