The Bosch Rexroth DR30-5-5X/100Y (R900596339) is a high-performance industrial hydraulic valve designed for reliable pressure reduction to a preset value. This mechanically actuated valve features a spool symbol B A and is capable of handling a maximum pressure as specified in its product group ID. It has multiple ports and utilizes mechanical actuation for its operations.
With its subplate mounting design, the DR30-5-5X/100Y conforms to the ISO connection diagram standards, ensuring compatibility and ease of integration into various hydraulic systems. The valve allows for a maximum flow rate as indicated by its specifications, and it is equipped with NBR seals suitable for hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC.
The DR series pressure valves are pilot-operated and controlled from the secondary circuit. They are composed of a main valve with a spool insert and a pilot control valve with an adjustable pressure element. In their default state, these valves permit unrestricted flow from channel B to channel A. The system's pressure balance is maintained through careful adjustment of the spring tension against the pressure in channel A.
Additional features include an optional check valve for free return flow from channel A to channel B and an external pilot oil return into the tank via a control line. For monitoring purposes, there's also a provision for connecting a pressure gauge to track the reduced pressure in channel A.
This Bosch Rexroth valve offers various adjustment types including rotary knobs and lockable rotary knobs with or without scales. It is designed for subplate mounting but can also be configured as a cartridge valve or threaded connection depending on specific requirements. The size of this component series X indicates its dimensions while its maximum operating pressure (bar) and maximum flow rate (l/min) define its performance capabilities within hydraulic systems.

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.
