Description

A cartridge-style pilot-operated spool-type relief valve

SYMBOL

Up all

Technical Feature

OPERATION:
The valve prevents flow from ① to ② until pressure at ① exceeds the set Cracking
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.
