The Bosch Rexroth DR6DP2-5X/210YM/12 (R900434477) is a high-performance industrial hydraulic valve designed for reliable pressure reduction from the supply pressure to a set value. This direct-actuated spool valve is part of the DR series, offering precise control for hydraulic systems. It features a pressure adjustment range up to 210 bar and an adjustable spindle with an external hexagon and protective cap, which allows for easy setting of the desired pressure.
The valve's design includes a pilot oil return, external measuring port with SAE thread, and it operates with a maximum pressure capability. The model supports a maximum flow rate and is intended for subplate mounting, following the NFPA T3.5.1 R2 D03 and ISO 6264 patterns. The DR6DP2-5X/210YM/12 also provides flexibility in actuation types, including mechanical actuation through various adjustment types such as rotary knobs or threaded pins with hexagons.
This Bosch Rexroth valve comes equipped with NBR seals, making it compatible with hydraulic fluids like HL, HLP, HLPD, HVLP, HVLPD, and HFC. It has multiple ports for connectivity and features an external leakage oil discharge via channel TY to ensure system cleanliness.
The unit's robust construction includes an optional check valve for free flow back from channel A to channel P and a pressure gauge connection for monitoring secondary pressure levels effectively. With its size specification and weight considerations accounted for during design, the DR6DP2-5X/210YM/12 ensures consistent performance in various hydraulic applications requiring precise pressure control.

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.
