The Bosch Rexroth DR10G5-4X/200YM (R900413544) is a high-performance industrial hydraulic valve designed for reliable pressure reduction to a predefined setting value. This direct-actuated spool valve is characterized by its P A spool symbol, indicating its function as a pressure reducing valve with ports P and A. It is capable of handling a maximum pressure that ensures its suitability for demanding applications.
The valve features mechanical actuation and comes in a size that corresponds to CETOP D standards, which makes it compatible with common industry mounting patterns. It offers subplate mounting and utilizes NBR seals, ensuring compatibility with various hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC.
With an ISO connection diagram and multiple switching positions, the DR10G5-4X/200YM provides flexibility in hydraulic circuit design. The weight of the unit reflects its robust construction suitable for industrial environments. Additionally, the option to include a check valve for free return flow from channel A to B in the subplate mounting version enhances its versatility.
The design of this Bosch Rexroth valve incorporates a screw-in cartridge valve cartridge within the housing. In its rest position, the valve allows free flow from inlet to outlet channels until the set spring pressure is exceeded, triggering the pilot poppet and activating control mechanisms to maintain constant outlet pressure.
This particular model offers various adjustment types including rotary knob options both with and without scales, sleeve with hexagon and protective cap, and lockable rotary knobs for precise control over system pressure settings. The external pilot oil return via port Y adds to the reduced pressure set by the spring chamber.
In summary, Bosch Rexroth's DR10G5-4X/200YM is engineered for optimal performance in reducing system pressures within hydraulic systems while providing robustness and adaptability through its design specifications and optional features.

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.
