The Bosch Rexroth DR10DP1-4X/150YM (R900500256) is a high-performance industrial hydraulic valve, designed for reliable pressure reduction to a preset value. This direct operated pressure reducing valve is mechanically actuated and comes in a 3-way version, ensuring the limitation of system pressure within secondary circuits. The valve is characterized by its spool symbol P → A and features maximum pressure capabilities that align with its product group specifications. With the ability to handle a variety of hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC, this valve is versatile in its applications. Its seals are made from NBR to ensure durability and resistance against various fluids. The DR10DP1-4X/150YM allows for unobstructed flow from channel B to A in its initial position while maintaining constant pressure levels through an adjustable compression spring mechanism. The unit includes an internal supply of signal and pilot oil via the control line from channel A and accommodates external leakage oil discharge through channel TY. An optional check valve can be installed for free flow back from channel A to B. Additionally, it features a pressure gauge connection for monitoring secondary pressure. Designed for subplate mounting with porting pattern according to DIN Form D and ISO standards, this Bosch Rexroth valve offers various adjustment types including a rotary knob and threaded pin with hexagon and protective cap—both lockable or with scale options. It has been engineered for use within a specified size range denoted by CETOP D standards and can handle maximum operating pressures and flow rates as defined by its component series X designation. The DR10DP1-4X/150YM's robust construction ensures it meets the demands of industrial hydraulic systems where precise pressure control is essential.

The valve type DR 10 DP is a direct operated pressure reducing valve in 3-way version, i. e. with pressure limitation of the secondary circuit.
It is used to limit a system pressure.
The secondary pressure is set via the adjustment type (1).
The valve is open in initial position. Hydraulic fluid can flow from channel B to channel A without restrictions. The pressure in channel A is simultaneously applied via the control line (4) at the piston area opposite the compression spring (3). If the pressure in channel A exceeds the value set at the compression spring (3), the control spool (2) moves to control position and keeps the set pressure in channel A at a constant level.
Signal and pilot oil are supplied internally via the control line (4) from channel A.
If the pressure in channel A increases further due to an external force effect at the actuator, it pushes the control spool (2) even further against the compression spring (3).
In this way, channel A is connected to channel T(Y) via the control edge (5) at the control spool (2). So much hydraulic fluid is discharged into the tank that the pressure can only increase slightly.
The leakage oil discharge from the spring chamber (6) is always effected externally via channel T(Y).
For the free flow back from channel A to channel B, a check valve (7) can optionally be installed.
A pressure gauge connection (8) allows for the control of the secondary pressure.
