Leading Wholesale Supplier of Proportional Relief Valves in China

Beyond Fluid offers proportional relief valves that open when system pressure reaches the set pressure and close when it falls below. Multiple springs are available to select different set pressure ranges. Back pressure (the pressure at the valve outlet) increases the set pressure of these valves.

These proportional relief valves open gradually with increasing pressure and do not have a rated capacity at a specific pressure rise (accumulation). A variety of end connections are available, including female/male NPT, BSPT, BSPP, metric threads, and double ferrule compression fittings.

These valves ensure precise pressure control and prevent spikes in hydraulic, gas, and fluid systems.
