The Bosch Rexroth DR6DP2-5X/75YMSO149 (R900722938) is a high-performance direct operated pressure reducing valve designed for subplate mounting with porting patterns according to DIN form A and ISO standards. This valve is tailored for applications where precise pressure limitation of a secondary circuit is essential. It operates by allowing hydraulic fluid to flow freely from channel P to channel A when in the initial position, with the secondary pressure set via an adjustable control.
The DR6DP2-5X/75YMSO149 features an internal control line that applies pressure from channel A to a piston, which acts against a compression spring. When the pressure in channel A exceeds the set value, the control spool moves into position to maintain a constant level of set pressure. In response to external forces that further increase the pressure in channel A, the valve discharges excess hydraulic fluid into the tank through channel TY, ensuring that the pressure rise is minimal.
Additionally, this model includes an external leakage oil discharge from its spring chamber via channel TY. An optional check valve can be installed for free flow back from channel A to P, enhancing versatility. For monitoring purposes, there's a provision for connecting a pressure gauge to keep track of secondary pressure levels.
The Bosch Rexroth DR6DP2-5X/75YMSO149 offers various adjustment types including rotary knob and threaded pin with hexagon and protective cap—both lockable rotary knob with scale and non-lockable versions are available. It comes in component series X and can handle maximum operating pressures up to bar levels while accommodating maximum flow rates measured in liters per minute (l/min). Its robust construction and precision engineering make it suitable for demanding applications where maintaining consistent system pressures is critical.

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.
