The Bosch Rexroth DR10G5-4X/200YM/12 (R900347548) is a sophisticated pilot-operated pressure reducing valve designed to effectively manage system pressure by reducing it to a desired level. This valve is particularly characterized by its screw-in cartridge and housing, which can be optionally accompanied by a check valve for subplate mounting configurations. In its default state, the valve remains open, allowing hydraulic fluid to flow unimpeded from the inlet to the outlet channel.
The system's pressure is regulated through the main control spool, which is influenced by spring tension and hydraulic pressure from the outlet channel. When the outlet pressure surpasses a pre-set threshold on the spring, a pilot poppet activates, redirecting fluid into the spring chamber and prompting the main control spool to adjust and maintain consistent outlet pressure.
This model offers versatility in installation with options for subplate mounting in accordance with ISO standards or as a threaded connection when utilized as a cartridge valve. Users can benefit from various adjustment types including a rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, or rotary knob with scale to fine-tune pressure settings.
The DR10G5-4X/200YM/12 operates within a maximum pressure rating specified for its size and component series X; X Maximum operating pressure bar. It provides reliable performance in maintaining set reduced pressures while accounting for additional pressure present in port Y during operation. With these capabilities, this Bosch Rexroth valve stands out as an essential component for precise hydraulic control in various 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.
