The Bosch Rexroth 3DREM16P-7X/250YG24K4V (R901261666) is a high-performance industrial hydraulic valve designed for precise pressure reduction and control in hydraulic systems. This valve operates through an electrical actuation with an external amplifier, ensuring reliable pressure adjustments to match the command value signal. With its spool symbol P A, the valve is capable of handling a maximum pressure with utmost efficiency.
The 3DREM16P-7X/250YG24K4V features a number of ports and utilizes a subplate mounting type of connection, conforming to CETOP D standards. It is equipped with an electrical connector pole PE and supports a supply voltage of 24 VDC. The robust design includes FKM seals which are compatible with various hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR.
This model's functionality includes both pressure reduction from P to A and limitation from A to T to manage system pressures effectively. The proportional solenoid operation allows for smooth actuation by the proportional solenoid with central thread and detachable coil. The valve's linear pressure-command value characteristic curve ensures precise control for applications requiring accurate pressure regulation.
For installations requiring pilot oil supply variations, the 3DREM16P-7X/250YG24K4V offers configurations for both external and internal pilot oil supplies with separate returns directed to the tank via port Y external. This flexibility allows for integration into various hydraulic circuit designs.
The Bosch Rexroth 3DREM16P-7X/250YG24K4V is designed for subplate mounting with porting patterns according to DIN form A and ISO standards. It has a maximum operating pressure rating of bar and can handle flow rates up to l/min. An optional spring-loaded pressure relief valve can be installed for maximum pressure limitation preset based on the relevant pressure rating. This ensures additional safety measures against excessive electric control currents that could lead to increased pressures in port A.

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%. |
