The Bosch Rexroth DR10DP2-4X/25YM (R900500563) is a direct-operated pressure reducing valve designed for subplate mounting with a porting pattern according to DIN Form D and ISO standards. It serves the purpose of limiting system pressure by maintaining a constant level in the secondary circuit. The valve ensures free flow from channel B to channel A in its initial position, allowing hydraulic fluid to move unrestrictedly. This model features various adjustment types, including a rotary knob, threaded pin with hexagon and protective cap, lockable rotary knob with scale, and a rotary knob with scale for precise control of the secondary pressure. The valve's functionality includes an internal pilot and signal oil supply via the control line from channel A, ensuring efficient operation. As pressure in channel A exceeds the set value on the compression spring, the control spool shifts to maintain consistent pressure. External forces further increasing channel A's pressure cause additional movement against the spring, connecting channel A to channel TY through the control edge on the spool. This action allows excess hydraulic fluid to discharge into the tank, preventing undue pressure rise. The DR10DP2-4X/25YM also features an external leakage oil discharge via channel TY from its spring chamber. For applications requiring reverse flow from channel A back to channel B without restrictions, an optional check valve can be installed. Monitoring and maintenance are made convenient with a pressure gauge connection for secondary pressure checks. The valve is designed for durability and performance with its size tailored for specific operational requirements—supporting maximum operating pressures and flow rates as defined by its component series designation. In summary, this Bosch Rexroth valve is versatile and reliable for applications requiring precise secondary pressure control within hydraulic systems.
