Designed for uni-directional flow control of fluids and gases in process and instrumentation applications Pressure rating: 6000 psig (414 bar) Body material: ASTM A276 Type 316 Spring material: 316 stainless steel Operating temperature range: –26 to +204°C Blow-out resistant seat design Back-stopped poppet minimizes spring stress Crack pressure: 25 psig (1.75 bar) Reseal pressure: 4 psig (0.28 bar) less than cracking pressure Factory tested for crack and reseat Fluorocarbon elastomer seat/seal
Note
Check valves that have not been actuated for some time may initially crack at higher than the quoted crack pressure.
