WebJan 18, 2007 · How a pilot-operated relief valve works Pump flow enters the inlet port and flows to the circuit and through the control orifice to the top side of the balanced piston or poppet. It also travels up to the pilot section’s spring-loaded poppet, where it is blocked. WebA relief valve works by reducing the pressurized fluid via an open path. As fluid begins to rise, the force from that pressure is applied to the bottom of the spool or poppet. Which then encourages the relief valve to open slowly while maintaining pressure downstream. Relief valves experience pressure rise from load pressure, back pressure, and ...
