The Bosch Rexroth DR10-5-5X/100Y/12 (R900507099) is a sophisticated pressure reducing valve designed for precise control in hydraulic systems. This pilot-operated valve is engineered to modulate fluid flow from channel B to channel A without restriction when in a resting state, ensuring that hydraulic systems operate efficiently and effectively. The main valve, along with its main spool insert, works in conjunction with the pilot control valve, which includes a pressure adjustment element for fine-tuning system performance.
Key capabilities of this model include the ability to maintain a consistent reduced pressure level by balancing the force exerted by the pressure in channel A against the tension set by an adjustable spring mechanism within the pilot control valve. This balance ensures stability and responsiveness within hydraulic operations. Additionally, an external pilot oil return line ensures that any excess fluid is directed back into the tank, maintaining system integrity.
The DR10-5-5X/100Y/12 offers flexibility in installation and application with options for subplate mounting or threaded connections, and it can also be utilized as a cartridge valve. Users can benefit from various adjustment types tailored to their needs, including a rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, or rotary knob with scale for precise adjustments.
Designed to conform to ISO porting patterns and available with an optional check valve for subplate mounting configurations only, this model provides versatility for integration into diverse hydraulic systems. It boasts impressive specifications such as a maximum operating pressure of up to 315 bar and a maximum flow rate of 100 liters per minute.
Furthermore, the inclusion of a pressure gauge connection allows operators to monitor the reduced pressure in channel A continuously. The Bosch Rexroth DR10-5-5X/100Y/12 represents reliable technology for managing hydraulic pressure effectively across various applications.

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.
