The Bosch Rexroth 3DREPE6B-2X/25EG24N9K31/A1V (R900931050) is a direct operated proportional pressure reducing valve designed for industrial hydraulic applications. It is capable of converting an electric input signal into a proportional pressure output signal, ensuring precise control over hydraulic systems. The valve features a spool valve that is directly actuated, with a maximum pressure adjustment range up to 350 bar and an integrated concealed manual override for additional operational flexibility.
This model includes concealed auxiliary actuation and employs a spool symbol P A B A T for its operations. It is equipped with an electrical connection that conforms to the Connector pole PE standard according to DIN EN 175301-803 form A, ensuring reliable electrical interfacing. The product belongs to the industrial hydraulic valve category and has four ports for fluid passage.
The actuation type of this valve is electrical with integrated electronics, which simplifies installation and maintenance by eliminating the need for separate control units. It has been designed for subplate mounting with a connection pattern that aligns with ISO 4401 standards. The size of the valve corresponds to NG6/CETOP 03/D03 patterns, and it can handle a maximum flow rate of 15 liters per minute.
For its power requirements, the 3DREPE6B-2X/25EG24N9K31/A1V operates on a supply voltage of 24 VDC and features two switching positions. Its robust construction ensures durability while maintaining a weight of approximately 2.4 kilograms. The use of FKM seals allows compatibility with various types of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR.
Overall, this Bosch Rexroth proportional valve is engineered for high performance in industrial environments where precise pressure control is essential. Its integrated electronics and subplate mounting design make it an efficient solution for modern hydraulic systems requiring reliable operation under varying pressures and flow conditions.

Industrial hydraulic valve in a high performance range. Reliable reduction of the pressure to the command value signal.
Unpacked Weight: 1.721 kg
The 3-way pressure reducing valve type 3 DREP 6.. is direct operated by proportional solenoids. It is intended for the conversion of an electric input signal into a proportional pressure output signal. The proportional solenoids are controllable, wet-pin DC solenoids with a central thread and a detachable coil. The solenoids are controlled optionally either by external control electronics (type 3DREP) or by the integrated control electronics (type 3DREPE).
Set-up:
The valve basically consists of:
Housing (1) with connection surface Control spool (2) with pressure measuring spool (3, 4) Solenoids (5, 6) with central thread optional integrated control electronics (7)Function:
The pressure in A or B is set by means of the proportional solenoids. The amount of the pressure depends on the current. With de-energized solenoids (5, 6), the control spool (2) is held in the central position by means of the compression springs (8). Ports A and B are connected with T so that the hydraulic fluid can flow to the tank without obstructions. By energizing a proportional solenoid, e.g. solenoid "a" (5), the pressure measuring spool (3) and with it the control spool (2) are moved to the right. This opens the connection from P to B and A to T via orifice-type cross-sections with progressive flow characteristics. With the surface of the pressure measuring spool (4) the pressure that builds up in channel B acts on the control spool and against the solenoid force. The pressure measuring spool (4) is supported by solenoid "b". If the pressure exceeds the value set at solenoid "a", the control spool (2) is pushed back against the solenoid force and connects B with T until the set pressure is reached again. The
pressure is proportional to the solenoid current. When the solenoid is switched off, the control spool (2) is returned into the central position by the compression springs (8). An optional hand override (9, 10) allows control spool (2) to be moved without solenoid energization.
Notice:
Accidental activation of the hand override may lead to uncontrolled machine movements!
Valve with two spool positions (type 3DREP..A.. or 3DREP..B..):
The function of this valve version basically corresponds to the valve with three spool positions. The 2 spool position valve is, however, only equipped with solenoid “a” (5) or solenoid “b” (6). Instead of the 2nd proportional solenoid, a plug screw (11) is installed.
Notice:
The tank line must not be allowed to run empty. With corresponding installation conditions, a preload valve (preload pressure approx. 2 bar) must be installed.
