Series Stainless IRV Industrial Relief Valve
Brand: Generant Inc
The 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.
Features- Supplied factory preset set and permanently locked for tamper proof service
- 100% factory tested for leakage, crack and reseal performance
- High flow capacity and excellent reseal performance
- Available in NPT, metal to metal face seal and Bi-lok dual ferrule tube connections
- Discharge to atmosphere or a wide variety of inline piping configurations
- Optional deflector cap available for diverting exhausted gas to atmosphere
- Available cleaned and packaged for oxygen service
