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. This cartridge relief valve offers a smooth transition
in response to a load change in a hydraulic circuit. -
