Description

A screw-in, cartridge-style, direct-acting, differential area, poppet-type hydraulic relief valve for use as a pressure limiting device in more demanding hydraulic circuits, requiring low hysteresis and low internal leakage.

Operation

The INRV08-22 blocks flow from port 1 to port 2 until sufficient pressure is present at port 1 to force the poppet from its seat. The cartridge offers smooth transition in response to load changes in common hydraulic circuits. Note: INRV08-22 may be used in cross-over relief applications (back pressure on port 2) with the use of the "C" double back-up ring seal option. See Ordering Table.
