The Bosch Rexroth DR10DP2-4X/210YV/12 (R978903599) is a direct operated pressure reducing valve designed for subplate mounting with a porting pattern according to DIN Form D and ISO standards. This model is part of the DR DPX.Y series, which is known for its capability to limit system pressure by maintaining a constant level in the secondary circuit. The valve's secondary pressure is adjustable through various adjustment types, which include options such as a rotary knob, a threaded pin with hexagon and protective cap, a lockable rotary knob with scale, or a rotary knob with scale. Featuring an initial open position, the DR10DP2-4X/210YV/12 allows unrestricted fluid flow from channel B to channel A while simultaneously applying pressure via the control line at the piston area against a compression spring. When the set pressure value is exceeded, the control spool moves into position to maintain consistent secondary pressure. Signal and pilot oil are supplied internally from channel A. In cases where external forces increase channel A's pressure further, the control spool counteracts by connecting channel A to channel TY through the control edge on the spool, allowing excess hydraulic fluid to discharge into the tank and preventing significant pressure rises. This model also features external leakage oil discharge via channel TY and offers an optional check valve for free flow back from channel A to B. Additionally, it provides a pressure gauge connection for monitoring secondary pressure. The Bosch Rexroth DR10DP2-4X/210YV/12 valve supports maximum operating pressures up to bar levels specified in its documentation and can handle maximum flow rates in liters per minute as indicated by its size and component series designation. It's engineered for reliability and precise control in hydraulic applications where regulation of secondary circuit pressure is critical.
