Series Stainless CRV Cryogenic Relief Valve
Brand: Generant Inc
The Generant Series Stainless Steel CRV Cryogenic Relief Valve is a spring reference over pressure protection device.
The Stainless CRV is supplied cleaned and packaged for oxygen service making it an ideal choice for most cryogenic relief valve applications.
The valve can be ordered with set pressures ranging from psig: 10 to 750 (kPa: 69 to 5,170, bar: 0.69 to 51.7) and come factory preset and permanently locked.
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.
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 can be specified with PCTFE (set pressures above psig: 50 (kPa: 354, bar: 3.54), Viton, and Fluorsilicone seals.
Features- Available in NPT, metal to metal face seal and Bi-lok dual ferrule tube connections
