Parker HPRVS4M4F-EPR-K2-500 Proportional Relief Valve

Parker HPRVS4M4F-EPR-K2-500 Proportional Relief Valve from Parker Hannifin is a hydraulic component designed to regulate system pressure by releasing excess fluid in proportion to a control signal. The valve features 1/4" M x F porting, enabling straightforward integration into standard hydraulic circuits with male and female connections. As part of Parker’s HPRV family, this proportional relief valve provides controlled relief rather than fixed setting, helping protect components and maintain stable operation under varying load conditions. The exact configuration is captured in the model number HPRVS4M4F-EPR-K2-500, which identifies the valve’s series and porting arrangement. Intended applications include hydraulic power units and industrial machinery where precise, adjustable relief is required to prevent overpressure and ensure smooth actuation of downstream valves and cylinders. For installation and performance specifics beyond port size—such as relief setting range, actuation signal, and mounting requirements—consult Parker’s official documentation for the HPRVS4M4F-EPR-K2-500.
