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 E-PSRV2-08 prevents flow from 1 to 2 until pressure at 1 exceeds the set crack pressure and opens the pilot section. The pilot flow creates a pressure differential across the spool which causes the valve to open allowing flow from 1 to 2 protecting the circuit from over pressurization.
This cartridge relief valve offers a smooth transition in response to a load changes in a hydraulic circuit.
FEATURES
* Adjustments cannot be backed out of the valve.
* Adjustments prohibit springs from going solid.
* Hardened spool and cage for long life.
* Fast, smooth response to pressure surges.
* Industry common cavity.
