HYRV10-23 (Pilot Operated Relief Valve)
Description:
A cartridge-style pilot-operated spool-type relief valve.
Operation:
The valve 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 change in a hydraulic circuit.
