CRV Stainless
The Generant Series CRV SS, Stainless Cryogenic Relief Valve is a direct-acting spring reference over pressure protection device. The Stainless CRV is supplied cleaned and packaged for oxygen service. The valve can be ordered with set pressures ranging from 10 to 750 PSIG (0.7 to 51.7 bar) and comes factory preset and permanently locked. Relief pressure cannot be altered or adjusted in the field. Seat and poppet geometry combined with optimized spring ranges provide high flow rates with minimum pressure accumulation. Compact design and availability of a variety of inlet and outlet configurations reduces size and piping requirements.
