Hydraulic Symbol
Description
A screw-in, cartridge-style, pilot-operated (two-stage), spool-type hydraulic relief valve, intended for use as a pressure limiting device in demanding hydraulic circuits which require fast response and low hysteresis, low leakage and low pressure overshoot.
Operation
The INRV10-23 blocks flow from port 1 to port 2 until sufficient pressure is present at port 1 to force the piloting relief off its seat, allowing the main spool to shift, opening port 1 to port 2. Note: The INRV10-23 may be used in cross-over relief applications; however, it is not recommended for use as in parallel cross-over relief or anti-cavitation applications. Consult factory for proper flow path connections.
