Air bleed off/Air admittance valve
Air bleed off/Air admittance valve
(OP)
Hi there. I have a vessel that is to be filled with water and hydro tested. Water will be entering at a rate of 100gpm so air must be purged at the same rate. The vessel will be pressured up to 10,000 psi and then drained. I am looking for a valve capable of allowing air out till the tank is full of water then retain the water at 10,000psi and finally allowing air in as tank is drained. Perhaps someone can advise me as to if such valves exist and where they can be procured.
Regards

To empty the tank, reverse the process, open slowly the drain to depressurize, the open the vent and drain completely the vessel.
Why would you use a complex and expensive valving arrangement which is useless after the hydrotest.
