The DR10DP1-4X/75YM/12 pressure reducing valve belongs to the DR Pressure Reducing Valves series manufactured by Bosch Rexroth and is applied to maintain a stable downstream pressure in hydraulic automation circuits. The NG10 valve size determines interface dimensions suited for medium-flow installations, while subplate mounting permits removal without disturbing hard lines. An ISO 5781 porting pattern matches common manifold layouts, and installation in any position gives flexibility during system assembly. Pilot oil is supplied internally so the valve derives its control signal directly from inlet pressure, and the input side withstands up to 315 bar of operating pressure before regulation begins.
The unit accommodates 80 L/min when fitted on a subplate, and the same 80 L/min rating applies if the flow passes through threaded connections in a block, ensuring equal capacity across mounting styles. A nominal pressure limit of 315 bar safeguards downstream components, and pilot oil returns externally to prevent heat accumulation in the main body. NBR seals provide compatibility with standard mineral oils and keep leakage low during extended duty. The assembled valve weighs 3.2 kg, allowing manual installation without lifting equipment and keeping overall manifold mass moderate.
