The Bosch Rexroth DR10DP2-4X/25Y (R900505901) is a direct-operated pressure reducing valve designed for subplate mounting with porting patterns that adhere to DIN Form D and ISO standards. This valve serves the purpose of limiting system pressure by setting the secondary pressure through various adjustment types, which include options such as a rotary knob, threaded pin with hexagon and protective cap, lockable rotary knob with scale, and a rotary knob with scale. The model features an open initial position allowing hydraulic fluid to flow from channel B to channel A without restrictions. The DR10DP2-4X/25Y operates by applying the pressure in channel A via the control line at the piston area opposite the compression spring. When this pressure surpasses the set value of the compression spring, the control spool moves into a control position maintaining a constant level of set pressure in channel A. An increase in channel A's pressure due to external forces will cause more displacement of the control spool against the compression spring, connecting channel A to channel TY through the control edge on the control spool. This action discharges enough hydraulic fluid into the tank to prevent any significant rise in pressure. Furthermore, leakage oil from the spring chamber is discharged externally via channel TY. For reverse free flow from channel A back to channel B, there's an option for installing a check valve. The inclusion of a pressure gauge connection facilitates monitoring of secondary pressure. The Bosch Rexroth DR10DP2-4X/25Y valve is designed for high-performance applications with its robust construction ensuring reliable operation under maximum operating pressures and flows as defined by its size and component series specifications.
