The Bosch Rexroth 3DREP6A-2X/25EG24XEJ/V (R901025332) is a high-performance industrial hydraulic valve designed for reliable pressure reduction to a preset command value signal. This direct-actuated spool valve features an electrical connection with a cable gland and terminal box, ensuring secure and efficient electrical integration. With a pressure adjustment range of up to bar and the ability to manage a maximum flow of l/min, this valve is well-suited for demanding applications requiring precise pressure control. The model is equipped with wet-pin DC solenoids that are controllable via external electronics, translating electrical input signals into proportional pressure output signals. The robust housing accommodates a subplate mounting connection, conforming to NFPA T3.5.1 R2 D03 and ISO 4401 standards, which ensures compatibility with various hydraulic systems. Additionally, the valve supports numerous hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. The 3DREP6A-2X/25EG24XEJ/V also boasts compliance with CE directives and the explosion protection directive EU for safe operation in potentially explosive atmospheres. Its design includes a single solenoid for the two-position version or dual solenoids for three-position control—each solenoid influencing the control spool position and thereby regulating the pressure output proportionally to the current supplied. This unit's construction features FKM seals for enhanced durability against harsh fluids and operating conditions. The model's size corresponds to CETOP D03 specifications with a maximum operating pressure of bar. The type of protection offered by this valve is Ex eb mb IIC T4 Gb according to EN IEC standards, making it suitable for areas where explosion protection is paramount. In summary, the Bosch Rexroth 3DREP6A-2X/25EG24XEJ/V (R901025332) stands out as an advanced solution for precise hydraulic pressure management in industrial settings that demand reliability and safety in explosive environments.

PRESSURE REDUCING VALVE 3DREP6A-2X/25EG24XEJ/V

Size 6, P → A / A → T, electrical with external electronics, 24 V DC

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

Unpacked Weight: 2.620 kg

3-way version For intended use in potentially explosive atmosphere For subplate mounting Porting pattern according to ISO 4401-03-02-0-05 (but without locating hole) Wet-pin DC solenoids Solenoid coil is rotatable by 90° Electrical connection as individual connection with cable gland

The 3-way pressure reducing valve type 3 DREP 6.. is direct operated by proportional solenoids. It converts an electrical input signal into a proportional pressure output signal.

The proportional solenoids are controllable wet-pin DC solenoids. The solenoids are controlled by external control electronics.

Set-up:

The valve basically consists of:

Housing (1) with connection surface Control spool (2) with pressure measuring pins (3, 4) Solenoids (5, 6) with central thread

Function:

The pressure in A or B is set by means of the proportional solenoids. The amount of the pressure depends on the current. 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 off to the tank without obstructions. By energization of a proportional solenoid, e. g. solenoid “b" (5), the pressure measuring pin (4) and with it the control spool (2) are moved to the left. This opens the connection from P to A and B to T via orifice-type cross-sections with progressive flow characteristics. With the surface of the pressure measuring pin (3) the pressure that builds up in channel A acts on the control spool and against the solenoid force. The pressure measuring spool (3) is supported by the solenoid "a". If the pressure exceeds the value set at solenoid “b”, the control spool (2) is pushed back against the solenoid force and connects A with T until the set pressure is achieved 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).

Notice:

Regarding valves of version 3DREP 6 C, only one solenoid may be actuated at a time.

Type 3DREP 6..2X/..XE..

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.

Valve with two spool positions (type 3DREP..A...):

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 "b" (5). Instead of the 2nd proportional solenoid, a plug screw (7) is installed.

The type-examination tested valve solenoid is equipped with a terminal box and a type-tested cable gland. The connection is polarity-independent.

Notice:

Corresponding to the rated current, a fuse according to DIN 41571 and EN / IEC 60127 has to be connected upstream of every valve solenoid (max. 3 x Irated).

The shut-off threshold of the fuse has to match the prospective short-circuit current of the supply source.

The prospective short-circuit current of the supply source may amount to a maximum of 1500 A.

This fuse may only be installed outside the potentially explosive area or must be of an explosion-proof design.
