While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Bosch Rexroth directly.***
The Bosch Rexroth 3DREPE6B-2X/25EG24K31/F1V (R901014844) is a high-performance industrial hydraulic valve designed for precise pressure reduction to a command value signal. This direct-actuated spool valve is equipped with electrical actuation through integrated electronics, providing reliable control for hydraulic systems. It features a pressure adjustment range of up to bar and a spool symbol of P B B T, ensuring versatility in application. The maximum pressure capacity of the valve is bar, while the maximum flow rate it can handle is l/min, suitable for various hydraulic flow requirements. The valve offers multiple ports for connectivity and comes with an electrical connection via a Connector pole PE conforming to DIN EN standards. Its subplate mounting design follows the connection diagram specifications of NFPA T.. R D Size CETOP D and ISO 4401, facilitating easy installation and compatibility with standard interfaces. The supply voltage required for operation is VDC, and it has two switching positions. Designed with durability in mind, the 3DREPE6B-2X/25EG24K31/F1V features FKM seals compatible with various types of hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. Its robust construction ensures long-lasting performance even under demanding conditions. The valve's functionality revolves around its ability to set pressure in ports A or B through its proportional solenoids. These solenoids are wet-pin DC types that can be easily controlled to achieve desired pressure levels proportional to the electric current supplied. An optional hand override feature allows manual control in the absence of solenoid energization but requires caution due to potential uncontrolled machine movements. In summary, the Bosch Rexroth 3DREPE6B-2X/25EG24K31/F1V offers precise electronic control over hydraulic pressures in industrial settings with its robust build quality and integrated electronics for efficient operation.

PRESSURE REDUCING VALVE 3DREPE6B-2X/25EG24K31/F1V

Size 6, P → B / B → T, electrical with integrated electronics, 24 V DC

Industrial hydraulic valve in a high performance range. Reliable reduction of the pressure to the command value signal.

Unpacked Weight: 1.720 kg

Direct operated proportional valve for controlling the pressure and direction of a flow Actuation by proportional solenoid with central thread and detachable coil For subplate mounting: Porting pattern according to ISO 4401 Manual override, optional Spring-centered control spool Type 3DREPE with integrated electronics (OBE) Type 3DREP with external electronics

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.
