Series Stainless IRV Industrial Relief Valve
Brand: Generant IncThe Generant Series Stainless Steel IRV Industrial Relief Valve is a spring reference over pressure protection device.
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 IRV is supplied with FKM seals. For severe service applications and set pressures above psig: 50 (kPa: 345, bar: 3.45), specify optional PTFE seals.
