The Generant Series CRV SS is a direct-acting spring reference over pressure protection device. Supplied cleaned and packaged for oxygen service, the valve can be ordered with set pressures ranging from 10 to 750 PSIG and comes factory preset and permanently locked.
Available in NPT, Metal to Metal Face Seal, and Dual Ferrule Tube connections. Compact design and availability of a wide variety of inlet and outlet configurations reduces size and piping requirements. Hydrogen compatible — all stainless design with spring located downstream of poppet seal.
