Pilot Operated Relief Valve
A hydraulic pilot-operated relief valve can release the surplus pressures to prevent damage of high pressure of the whole system. It will lift the seat to make the oil flow out to the oil tank once the pressure is over the preset pressure of the relief valve.
If you have a need of pilot-operated relief valves, Hydraflu hydraulcis can fulfill all your purchasing needs. We have plenty of hydraulic valves in both high and low pressure ranges. Our pilot-operated relief valves are well perforamnced smooth response, minimal pressure rise, and limited hysteresis.

Good Performance Gains Reputation
Hydraflu’s pilot-operated relief valves have Low-Latency, Accurate, and Stable Pressure Management. This is one of our most appreciated features by customers.
Widely Used In Agricultural and Machinery Industry
This series of pilot-operated relief valves has gained significant market share and widely replaced competitors’ hydraulic valves, thanks to its precise pressure adjustment range, high flow capacity, and suitability for high-pressure applications.
This design delivers quieter operation and reduced maintenance frequency by using a pilot operated relief valve to minimize the force required to drive the main valve. This reliability is particularly valuable for critical infrastructure and remote sites, where unscheduled downtime is exceptionally costly.
The cartridge ensures a smooth hydraulic transition in response to load changes, even in demanding circuits. This performance is characterized by smooth response, minimal pressure rise, and limited hysteresis.
The essential parts of a pilot-operated relief valve have two stages of poppets and two springs. One pilot control poppet lifts from its seat to cause the secondary poppet to lift and make the circuit flow.
