Ace Glass 8767-20 Adjustable Pressure Relief Valve, 3-50 psig, 1/4" NPT

The primary protection to personnel and equipment involved with static and dynamic pressured systems. This one-piece pressure relief valve is adjustable from 3 to 50 psig (for use with ACE pressure reactors) or 50 to 150 psig by simply adjusting set screws to desired cracking pressure. When pressure exceeds set cracking pressure, valve bleeds; when a safe lower pressure is realized, valve will reseal. Fabricated from 316 stainless steel with a Viton O-Ring. Ends are 1/4-inch NPT for connecting into Ace-Thred with a 5844 adapter.
