The Bosch Rexroth DR10G5-4X/200YMV/12 (R900539869) is a sophisticated pressure reducing valve designed for subplate mounting and is adept at modulating system pressure. The valve is primarily composed of a screw-in cartridge and housing, with the option to include a check valve. It operates in a normally open state, allowing hydraulic fluid to flow freely from the inlet to the outlet channel. The system's outlet pressure is regulated via a spring-loaded main control spool, which responds to pressure changes by moving to maintain a set pressure value.
This model features an external pilot oil return via port Y, ensuring consistent performance. For applications necessitating free return flow from channel A to B, an optional check valve can be installed in the subplate mounting version P. The DR10G5-4X/200YMV/12 offers various adjustment types for precise control, including rotary knob options—both with and without scale—sleeve with hexagon and protective cap, and lockable rotary knobs.
The unit adheres to ISO porting patterns for reliable integration into existing systems and boasts impressive durability with maximum operating pressures of up to 315 bar. As part of component series X and X, this model ensures compatibility and performance for industrial applications requiring meticulous pressure management.

The pressure valve type DR is a pilot-operated pressure reducing valve. It is used to reduce the system pressure.
It mainly consists of screw-in cartridge valve (cartridge) and housing, optionally with or without check valve (subplate mounting only).
In the rest position the valve is open. The hydraulic fluid is able to flow freely from the inlet channel via the main control spool (1) to the outlet channel. The pressure in the outlet channel is applied to the spring-loaded side of the main control spool (1) via the bore (2). At the same time, the pressure acts upon the side of the main control spool (1) that is opposite to the spring via the bores (3) and (4).
If the pressure in the outlet channel exceeds the value set at the spring (6), the pilot poppet (5) opens.
Hydraulic fluid flows from the spring-loaded side of the main control spool (1) via the nozzle (7) and the pilot poppet (5) into the spring chamber (8).
The main control spool (1) assumes its control position and keeps the value in the outlet channel set at the spring (6) constant. The pilot oil return from the spring chamber (8) is always realized externally via the Y port (9).
In subplate mounting version "P", a check valve (10) can be optionally installed for free return flow from channel A to B.

Notice!
The pressure in port Y is added 1:1 to the set reduced pressure.
