WebApr 14, 2024 · The principle of operation of the valve is relatively straightforward. When the pressure on the upstream side of the valve exceeds a setpoint, the valve opens to allow fluid to pass through to the downstream side, reducing the pressure differential. When the downstream pressure exceeds a setpoint, the valve will close, preventing further flow. WebJan 1, 2012 · Figure 2. Adjustable, direct-acting relief valve blocks flow through the valve until force of system pressure on the poppet overcomes the adjustable spring force and downstream pressure. Relief valves are also made to relieve flow in either direction. Fluid pressure at the other port acts on a shoulder on the plunger to open the valve.
