Description
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 10 to 750 Psig (0.69 to 51.7
Bar) 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 50 Psig (3.45 Bar), specify optional PTFE seals.
