The Bosch Rexroth DR6DP2-5X/25Y (R900465254) is a high-performance, industrial hydraulic valve designed for reliable pressure reduction from the supply pressure to a set value. This mechanically actuated valve is part of the direct operated pressure reducing valve series and functions as a 3-way version, ensuring pressure limitation in the secondary circuit. The DR6DP2-5X/25Y allows for free flow from channel P to A when in its initial position and maintains a constant level of set pressure in channel A via an adjustment type, which can be controlled through various optional adjustments such as a rotary knob or threaded pin with protective cap.
The valve features a spool symbol P A with maximum pressure capabilities and is suited for subplate mounting with connection diagrams conforming to NFPA T.. R D SizeCETOP D and ISO standards. It has multiple ports for efficient fluid control and includes NBR seals compatible with hydraulic fluids like HL, HLP, HLPD, HVLP, HVLPD, and HFC. The maximum flow rate is managed according to the size of the component series X, while the maximum operating pressure can reach up to bar levels specified by its design.
Additional functionalities include an external leakage oil discharge via channel TY from the spring chamber and an optional check valve for free flow back from channel A to channel P. Monitoring of secondary pressure is facilitated through a dedicated pressure gauge connection. The DR6DP2-5X/25Y's robust construction ensures durability and precision in controlling hydraulic pressures within various 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.
