The Generant Series Brass IRV is a spring reference over pressure protection device. Factory preset and permanently locked — relief pressure cannot be altered in the field. Seat and poppet geometry combined with optimized spring ranges provide high flow rates with minimum pressure accumulation.
Available in vent to atmosphere, inline, or deflector cap configurations. For severe service applications and set pressures above 50 PSIG, specify optional PTFE seals. Available cleaned and packaged for oxygen service.
