The Bosch Rexroth DR10-5-5X/100Y (R900596766) is a high-performance industrial hydraulic valve designed for reliable pressure reduction to a predetermined setting value. This mechanically actuated valve is part of Bosch Rexroth's product group and showcases a spool symbol of B A, indicating its flow path. It operates with a maximum pressure capacity and features multiple ports for versatile connectivity. The type of actuation is mechanical, ensuring robust and direct control. With a size designation of B, the DR10-5-5X/100Y can handle a substantial max flow rate, making it suitable for various hydraulic applications. It employs subplate mounting for secure installation and conforms to ISO connection diagrams, which facilitates its integration into standardized systems. The valve has multiple switching positions and comes with NBR seals that are compatible with hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC. Pressure valves like the DR10-5-5X/100Y function by allowing fluid to flow from channel B to channel A unrestrictedly in their rest position. When the pressure in channel A exceeds the spring-set value, the control spool begins to close off the flow. The balance between the pressure in channel A and the spring setting determines the reduced pressure level achieved by this valve. An external pilot oil return ensures proper functioning while an optional check valve can be installed for free return flow from channel A to B. Additionally, users can monitor pressure adjustments via a pressure gauge connection that controls reduced pressure in channel A. Available adjustment types for this model include options such as rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, or rotary knob with scale—offering flexibility according to user preferences. The DR10-5-5X/100Y also supports various pressure ratings and can include an optional check valve when subplate mounted. It is part of component series X which specifies its modern design attributes and confirms its capability to withstand maximum operating pressures up to specified bar levels while maintaining maximum flow rates expressed in liters per minute (l/min).

Pressure valves type DR are pilot-operated pressure reducing valves controlled from the secondary circuit.
The pressure reducing valves basically consist of the main valve (1) with main spool insert (3) and pilot control valve (2) with pressure adjustment element.
Basic principle:
In rest position, the valves are open. Hydraulic fluid can flow via the main spool insert (3) from channel B to channel A without restrictions. The pressure applied in channel A acts on the bottom of the main spool. Simultaneously, pressure is applied via the nozzle (4) to the spring-loaded side of the main spool (3) and via channel (5) to ball (6) in the pilot control valve (2). Similarly, it acts via nozzle (7), control line (8), check valve (9) and nozzle (10) on the ball (6). Depending on the setting of the spring (11), pressure builds up upstream of the ball (6), in channel (5) and in the spring chamber (12) holding the control spool (13) in open position. The hydraulic fluid in channel B can flow via the main spool insert (3) to channel A without restrictions until a pressure builds up in channel A exceeding the value set at the spring (11) and opening the ball (6). The control spool (13) is moved into closing direction.
The desired reduced pressure is reached if there is a balance between the pressure in channel A and the pressure set at the spring (11).
The pilot oil return from the spring chamber (14) is always realized externally via the control line (15) into the tank.
For the free return flow from channel A to channel B, a check valve (16) can optionally be installed.
A pressure gauge connection (17) enables control of the reduced pressure in channel A.
