150 - 550 PSIG (10.34 - 37.92 bar)
Description
The Generant Series RVA, Cryogenic Relief Valve is a spring reference over pressure protection device that meets the requirements of ASME BPVC Section XIII. RVA Series valves are designed for use on piping systems or liquid cylinders when an ASME Coded relief valve is required. Every RVA Series valve is supplied cleaned and packaged for oxygen service standard. Valves can be ordered factory-preset from 150 to 550 Psig (10.34 to 37.92 Bar) and are permanently locked. Seat and poppet geometry combined with optimized spring ranges provide consistent, high flow at allowable overpressures. The RVA is supplied with a Carbon-Filled PTFE seal.
