The Bosch Rexroth 3DREM10P-7X/315YG24K4V (R901213615) is a high-performance industrial hydraulic valve designed for reliable pressure reduction and regulation within hydraulic systems. This electrically pilot-operated 3-way pressure reducing valve features a proportional solenoid for precise control and can optionally include a maximum pressure limitation to safeguard against excessive pressures.
With its spool symbol P A, the valve facilitates the command value-dependent setting of reduced pressure at port A through its pilot control valve. It ensures that with a depressurized port P, startup jumps at the actuator are prevented, maintaining system stability. The pilot oil flow is meticulously managed through various components of the valve to achieve desired pressure reduction or limitation.
The Bosch Rexroth 3DREM10P-7X/315YG24K4V is designed for subplate mounting with connection diagrams conforming to NFPA T3.5.1 R2 D03 and CETOP D03 standards, as well as ISO 4401-03-02-0-05 standards. It operates on a supply voltage of 24 VDC and features an electrical connection via a Connector pole PE according to DIN EN specifications.
This model has a maximum operating pressure of 315 bar and can handle a maximum flow of up to 40 l/min, making it suitable for various industrial applications requiring precise pressure management. The type of actuation is electrical with external electronics, which means it requires an external amplifier for operation. The unit's weight is noted along with its compatibility with various hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, HFDR types.
Its construction includes FKM seals ensuring durability and chemical resistance in harsh environments. For those needing additional safety measures against overpressurization due to high electric control current at the proportional solenoid, an optional spring-loaded pressure relief valve can be included in the configuration.
In summary, the Bosch Rexroth 3DREM10P-7X/315YG24K4V offers advanced functionality for systems requiring precise electronic control over hydraulic pressures within demanding industrial applications.

The valves of type 3DRE(M) are electrically pilot-operated 3-way pressure reducing valves with pressure
limitation of the actuator. They are used for reducing a system pressure.
Technical set-up
The valve consists of two main assemblies:
Pilot control valve (1) with proportional solenoid (2) optionally with maximum pressure limitation (15) Main valve (3) with main spool (4)
Function
General function:
Command value-dependent setting of the pressure to be reduced in port A via the pilot control valve (1). With depressurized port P, the springs (5) and (6) hold the main spool (4) in its central position. In this way, a start-up jump at the actuator is prevented. Pilot oil flows from bore (7) via the flow controller (8), via the control chamber (11) to the throttle gap (9), via line (10) to port Y. This connection is to be lead into the tank at zero pressure.
Pressure reduction:
Build-up of the pilot pressure in the control chamber (11) as a function of the command value. Pressure build-up in the spring chamber (13) via nozzle (12) and movement of the main spool (4) to the right. Hydraulic fluid flows from P to A. The actuator pressure in port A is available in the spring chamber (14). Increase in the pressure in port A to the set pressure of the pilot control valve (1) leads to the movement of the main spool (4) to the left. Pressure in port A is almost identical with the set pressure at the pilot control valve (1).
Pressure limitation:
If the pressure in port A exceeds the set pressure of the pilot control valve (1), the main spool (4) is moved further to the left. This opens the connection from A to T and limits the pressure pending in port A to the set command value.
Type 3DREM
For hydraulic protection against an inadmissibly high electric control current at the proportional solenoid, which imperatively results in increased pressures in port A, you can optionally install a spring-loaded pressure relief valve as maximum pressure limitation (15).
The maximum pressure limitation is pre-set based on the relevant pressure rating.

Large temperature differences may lead to differing characteristic curves / values.
Pressure in port P dependent on the command value
| 1) | 1) With valve type DBEM and 3DREM, the manufacturing tolerance at the external amplifier can be changed using the command value attenuator potentiometer "Gw”. The digital amplifier is set using the "Limit” parameter. Here, the control current according to the technical data must not be exceeded. In order to be able to adjust several valves to the same characteristic curve, do not set the pressure higher than the maximum set pressure of the pressure rating with command value 100%. |
