We operate with a 100# open source steel tank. We have a steel McMaster 150 psi prv on the tank but are considering raising the psi value. Two times we have pressure tested the tank at 140 and 130 respectively and both times the prv was realeased at the end of the tests. Both times the prv released when we were opening a valve on the top of tank to release the air. My experience tells me simply grazing, touching, or working around the prv shouldn't set it off. Due to the prv failing to hold pressure until the conclusion of our tests my partner and I are debating on buying and installing a prv thats rated for 175-200psi.
At times our operating pressure will reach 120-130psi, with that in mind and the pressure test failing should we up the psi on our prv ? Also is there any reason as to why the prv at 150psi would be failing ?
