The Bosch Rexroth DR10DP2-4X/210Y/12 (R978901991) is a direct operated pressure reducing valve designed for precise control of system pressure in hydraulic applications. This model, part of the DR DP series, is a 3-way version that functions by limiting the secondary circuit's pressure. The secondary pressure can be set through an adjustment mechanism, providing flexibility in various hydraulic systems. In its initial position, the valve allows unrestricted flow from channel B to channel A, while simultaneously applying pressure from channel A to the piston area against a compression spring through a control line. When the pressure in channel A surpasses the spring's set value, the control spool shifts to maintain a constant level of set pressure within channel A. The valve features internal signal and pilot oil supply through the control line from channel A. Should there be an increase in pressure due to external forces acting on the actuator, it causes further displacement of the control spool against the spring. This action connects channel A to channel TY via a control edge on the spool, allowing excess hydraulic fluid to discharge into the tank and preventing significant pressure increases. Leakage oil from the spring chamber is discharged externally via channel TY. Additionally, for reverse free flow from channel A back to channel B, there is an option to install a check valve. The model also includes a pressure gauge connection for monitoring secondary pressure. This valve offers various adjustment types such as rotary knob and threaded pin with hexagon and protective cap; some models feature lockable rotary knobs with scale or without scale for precise adjustments. It is designed for subplate mounting with porting patterns according to DIN Form D and ISO standards. The Bosch Rexroth DR10DP2-4X/210Y/12 has specific size designations and component series that determine its maximum operating pressures (bar) and flow rates (l/min), making it suitable for diverse hydraulic control tasks where maintaining constant system pressures is crucial.
