The Bosch Rexroth DR6DP2-5X/25YM (R900472470) is a high-performance industrial hydraulic valve designed for reliable pressure reduction to a preset value. This direct-actuated spool valve is mechanically actuated and features a P A spool symbol, ensuring efficient flow from channel P to channel A with minimal restriction. The maximum pressure capacity of this product falls within the product group ID specifications, and it includes multiple ports for versatile connectivity. With mechanical actuation, the DR6DP2-5X/25YM valve offers precise control over system pressures by setting the secondary pressure through an adjustment type. In its default state, the valve allows unrestricted flow of hydraulic fluid while maintaining constant pressure levels in channel A via a control spool that reacts to changes in pressure against a compression spring. This valve's design includes internal signal and pilot oil routing from channel A and features a design that discharges excess hydraulic fluid into the tank to prevent overpressure. External leakage oil discharge is managed through channel TY. For applications requiring free flow back from channel A to channel P, an optional check valve can be installed. The DR6DP2-5X/25YM also provides a pressure gauge connection for monitoring secondary pressure levels. It is designed for subplate mounting with porting patterns conforming to DIN form A and ISO standards, including an optional locating hole. Users have several adjustment types at their disposal, including rotary knobs and threaded pins with protective caps, some of which are lockable or come with scales for precise adjustments. This model's specifications include various sizes in component series X, with maximum operating pressures reaching up to bar levels and maximum flow rates measured in liters per minute (l/min). The valve's seals are made of NBR material compatible with various hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC.
Size 6, P → A, mechanically actuated
Industrial hydraulic valve in a high performance range. Reliable pressure reduction to setting value.
Unpacked Weight: 1.5 kg
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.
