The Bosch Rexroth DR10DP3-4X/210YV/12 (R901200427) is a direct operated pressure reducing valve designed to effectively manage and limit system pressure within hydraulic applications. This model, part of the DR series, offers precision in controlling secondary circuit pressures through an adjustment type mechanism. The valve features an open initial position, allowing hydraulic fluid to flow from channel B to A without restrictions, while the secondary pressure is set via the adjustment type and maintained by a compression spring. Capable of handling maximum operating pressures and flow rates as specified by its design, this Bosch Rexroth valve ensures constant pressure levels in channel A even when external forces are applied. An internal control line supplies signal and pilot oil from channel A, while the control spool adjusts to maintain set pressure against the compression spring's force. Excess hydraulic fluid is directed to the tank through channel TY, ensuring only minimal pressure increases. The model includes features such as external leakage oil discharge via channel TY and an optional check valve for free flow back from channel A to B. Additionally, it offers a pressure gauge connection for monitoring secondary pressures and comes with various adjustment types including rotary knob options—with or without scale—and a lockable variant for secure settings. Designed for subplate mounting with porting patterns according to DIN Form D and ISO standards, this Bosch Rexroth valve caters to diverse hydraulic system requirements while ensuring reliability and high performance. The option for a check valve installation and different adjustment types adds versatility to its application across various hydraulic systems.
