1/2" MNPT Generant Cryogenic Relief Valve - 25PSI -196°C to 176°C

The Generant Series Brass CRV, Cryogenic Relief Valve is a spring reference over pressure protection device. The CRV incorporates Generant’s exclusive “Dirt Guard” feature which increases the valves ability to tolerate particulate contamination. This device is ideally suited for use as a “Blocked Line Safety” in cryogenic systems. The CRV is supplied cleaned and packaged for oxygen service. Relief pressure can not be altered or adjusted in the field. Seat and poppet geometry combined with optimized spring ranges provide high flow rates with minimum pressure accumulation. The Generant Cryogenic Relief Valve has a compact design and availability of a variety of inlet and outlet configurations reduces size and piping requirements. Relief pressure can be discharged to atmosphere or to a downstream connection. The CRV is supplied with Flourosilicone seals for set pressures from 10 – 49 Psig (0.7 – 3.4 Bar) and PCTFE seals for set pressures greater then 50 – 750 Psig (3.5 – 51.7 Bar)
