Product Overview
The Rexroth PR4-30/3,15-500RA01M01 is a pilot operated pressure relief valve engineered for precise system pressure limitation and overload protection in industrial hydraulic circuits. Manufactured by Bosch Rexroth, this valve utilizes a two-stage pilot operated design in which a small pilot stage senses system pressure and controls the main poppet, enabling smooth, accurate relief of excess flow back to tank. The PR4 series is designed for high-pressure hydraulic systems where stable pressure regulation, low hysteresis, and fast response are essential. With a nominal pressure setting of 500 bar and a pilot orifice designation of 3,15, this valve is suited for demanding applications requiring reliable pressure control and safe system protection.
