Powerhouse valve weeping

[SqrlHntr]

I got a Powerhouse valve that won’t seem to hold air back no matter what, it weeps through the barrel but operates fine otherwise. Tried with and w/o a regulator, tried firing while filling and verified striker is not hitting the valve face. Still no dice. Any advice for next steps?
Thanks in advance and happy shootin’!

Cothran valve I'd call and talk to Dan cothran the maker and see what he says to try

With Don's, Like most valves all it takes to have a valve leak is a micro spec of debris to get stuck between the stem and the seat. I'd take the valve apart flush all parts blow them off with compressed air and then re-assemble and see if the problem is gone.
If you still have a problem call Don and see what comes next.
