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.
Operation
The INRV12-26 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 (second stage) spool to shift, opening port 1 to port 2. The cartridge offers smooth transition in response to load changes in demanding hydraulic circuits. Note: The INRV12-26 cannot be used in crossover relief applications.
