Isn't there an ASHRAE standard or rule that states there can't be any shut off device on an HPCO? And I think it includes schraders too. Most (if not all) of the recips and screws I've worked on haven't had one unless someone added one. And usually it's a flare fitting that you can't put a core in anyway. I'd be very careful and at least isolate the discharge line and get the pressure down a little.

Farewell to foreign shores, We sail at break of day. Through our last night on shore, Drink to the foam. Until we meet once more. Here's wishing you a happy voyage home!
