The Bosch Rexroth DR6DP1-5X/210Y (R900481034) is a high-performance, direct-actuated industrial hydraulic valve designed for reliable pressure reduction to a preset value. This spool valve, marked by its DR 6 DP series designation, is engineered for mechanically actuated operations and is characterized by its P to A spool symbol. It can sustain a maximum pressure as denoted in its product group ID, with the ability to manage flow rates up to the specified max flow limit.
The valve boasts an array of features including subplate mounting for secure installation and compatibility with connection diagrams conforming to both NFPA T3.5.1 R2 and ISO standards. It offers flexibility in actuation types, such as mechanical actuation and has multiple ports for comprehensive hydraulic circuit integration.
This model comes equipped with NBR seals, ensuring compatibility with various hydraulic fluids like HL, HLP, HLPD, HVLP, HVLPD, and HFC types. The valve operates by allowing free flow from channel P to A until the pressure set by the adjustment type is reached. When exceeded, the control spool adjusts to maintain a constant level in channel A.
Additionally, this unit features options for secondary pressure monitoring through a pressure gauge connection and can be optionally fitted with a check valve for reverse free flow from A to P. The design allows for external leakage oil discharge via channel TY.
With multiple adjustment types available including rotary knob and threaded pin options—some of which are lockable or come with a protective cap or scale—this Bosch Rexroth valve provides versatility and precision in pressure settings. The DR6DP1-5X/210Y model ensures consistent performance under varying pressures with its robust construction and thoughtful engineering suited for demanding industrial applications.

The valve type DR 6 DP is a direct operated pressure reducing valve in 3-way version, i. e. with pressure limitation of the secondary circuit.
It is used to limit a system pressure. The secondary pressure is set via the adjustment type (4)
The valve is open in initial position. Hydraulic fluid can flow from channel P to channel A without restrictions. The pressure in channel A is simultaneously applied via the control line (6) at the piston area opposite the compression spring (3). If the pressure in channel A exceeds the value set at the compression spring (3), the control spool (2) moves to control position and keeps the set pressure in channel A at a constant level.
Signal and pilot oil come internally via the control line (6) from channel A.
If the pressure in channel A increases further due to an external force effect at the actuator, it pushes the control spool (2) even further against the compression spring (3).
In this way, channel A is connected to channel T(Y) via the control edge (8) at the control spool (2). So much hydraulic fluid is discharged into the tank that the pressure can only increase slightly.
The leakage oil discharge from the spring chamber (7) is always effected externally via channel T(Y).
For the free flow back from channel A to channel P, a check valve (5) can optionally be installed.
A pressure gauge connection (1) allows for the control of the secondary pressure.

Notice!
The curve development is maintained if the pressure is set lower according to the pressure rating.
The characteristic curves apply to the pressure at the valve output p = 0 bar across the entire flow range.
