Sun Hydraulics RPECLAV-1800PSI Pressure Reducing Valve

Sun Hydraulics RPECLAV-1800PSI is a pilot-operated, balanced-piston cartridge that regulates hydraulic pressure down to a nominal 1,800 psi. In operation, when the pressure at inlet port 1 reaches the valve’s set point, it opens to tank port 2 to throttle flow and hold the downstream pressure at the desired level. The device is normally closed and designed to be installed as a cartridge within a compatible Sun body, providing precise, downstream pressure control in hydraulic circuits. All Sun pilot-operated reducing and reducing/relieving cartridges include a 150-micron stainless-steel screen to protect the orifice from contamination, helping maintain reliable performance in dirty-system environments. This model is typically used in applications where stable downstream pressure matters—such as clamp or forming processes, test rigs, and general hydraulic control circuits—and is identified by the 1800 psi set point, with port configurations and mounting designed to integrate with Sun’s cartridge and body assemblies. For correct installation, replaceable in a compatible Sun hydraulic system, ensure the chosen body and porting match the RPECLAV family specifications and that system pressures align with the 1,800 psi nominal setting of this variant.
