The Bosch Rexroth DR10-5-4X/315YM (R900413543) is a high-performance industrial hydraulic valve that specializes in reliable pressure reduction to a preset value. This direct-actuated spool valve features a P A spool symbol and is designed for subplate mounting with CETOP size D connections, conforming to ISO standards. It is mechanically actuated, ensuring precise control over hydraulic systems.
This model boasts a maximum pressure rating and is equipped with NBR seals, making it compatible with various hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, and HFC types. The DR10-5-4X/315YM valve is distinguished by its robust construction which includes a screw-in cartridge valve cartridge and an optional housing with or without a check valve for subplate mounting only.
In its default state, the valve allows free flow of hydraulic fluid from the inlet to the outlet channel. The system's pressure is regulated by the main control spool in response to changes in the outlet channel pressure against the spring setting. An external pilot oil return via the Y port is required for this model.
For applications requiring free return flow from channel A to B, an optional check valve can be installed in version P of this subplate mounting valve. The DR10 series also includes various adjustment types such as rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, and rotary knob with scale for fine-tuning pressure settings.
With multiple ports and switching positions available, this Bosch Rexroth hydraulic valve caters to a wide range of flow requirements while maintaining consistent performance under varying operating pressures up to its maximum threshold. Its compact design ensures ease of integration into existing hydraulic systems while providing exceptional control and reliability for industrial applications.

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.
