The Bosch Rexroth DR10DP7-4X/150YM/12 (R978914609) is a high-performance direct operated pressure reducing valve designed for subplate mounting with a porting pattern in accordance with DIN Form D and ISO standards. This valve is part of the component series X and is capable of handling maximum operating pressures of up to 150 bar, ensuring reliable performance in demanding applications. It has been engineered to maintain a constant level of secondary circuit pressure, which can be precisely set via an adjustment type, such as a rotary knob or threaded pin with hexagon and protective cap. In its initial open position, the DR10DP7-4X/150YM/12 allows unrestricted fluid flow from channel B to A, while simultaneously applying pressure through the control line on the piston area opposite the compression spring. When the secondary pressure exceeds the set value, the control spool moves into position to stabilize this pressure. The internal supply of signal and pilot oil via the control line from channel A enhances the responsiveness and accuracy of regulation. Should an external force increase pressure in channel A, this valve discharges excess hydraulic fluid into the tank through channel TY, preventing significant pressure rise. Furthermore, it features an external leakage oil discharge from its spring chamber via channel TY. An optional check valve can be installed for free flow return from channel A to B. The DR10DP7-4X/150YM/12 also comes with a pressure gauge connection for monitoring secondary pressure levels. With various adjustment types available—including lockable rotary knobs with scale—this valve offers flexibility for different system requirements. Its design ensures that it can be integrated seamlessly into hydraulic systems requiring precise pressure reduction and regulation capabilities.
