The Bosch Rexroth DR6DP2-5X/210Y (R900413243) is a high-performance, industrial hydraulic valve that specializes in reliable pressure reduction from the supply pressure to a preset value. This direct operated pressure reducing valve is designed for subplate mounting and conforms to DIN and ISO porting patterns, ensuring compatibility with a wide range of systems. The model features mechanical actuation, allowing for precise control over hydraulic flow and pressure.
With its spool symbol P A, the DR6DP2-5X/210Y valve allows for unrestricted flow from channel P to channel A in its initial position. The secondary pressure can be finely adjusted using various optional adjustment types such as a rotary knob or threaded pin with hexagon and protective cap. For enhanced safety and convenience, options include a lockable rotary knob with scale or simply a rotary knob with scale.
The valve's maximum operating pressure reaches up to bar, while it can handle maximum flow rates of l/min, making it suitable for demanding applications. It features multiple ports and is equipped with NBR seals, ensuring compatibility with hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC.
Furthermore, the DR6DP2-5X/210Y includes an external leakage oil discharge via channel TY and the option to install a check valve for free flow back from channel A to channel P. A pressure gauge connection is also available for monitoring secondary pressure levels.
In summary, the Bosch Rexroth DR6DP2-5X/210Y offers robust construction and flexible configuration options that cater to various industrial requirements for precise pressure regulation within hydraulic systems.

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.
