The Bosch Rexroth 4WRE10E75-2X/G24K4/V (R900954102) is a high-performance industrial hydraulic valve designed for reliable control of oil flow direction. This direct actuated spool valve features a spool symbol E and is equipped with an external amplifier. It offers high accuracy due to its internal piston position feedback system. The valve is suitable for subplate mounting, with a connection diagram that adheres to NFPA T..R D SizeCETOP D and ISO standards.
This model has integrated electronics, type WRE...X..., and requires a supply voltage of 24 VDC. It has a nominal flow rate and can operate at a maximum pressure, ensuring robust performance for various applications. The electrical connection is facilitated by a Connector pole PE according to EN standards, contributing to its straightforward integration into hydraulic systems.
The proportional directional valve operates using proportional solenoids with central threads and detachable coils, which are controlled by the external electronics. It boasts a spring-centered control spool for precise operation. The number of switching positions allows for versatile control options within the system it's integrated into.
The 4WRE10E75-2X/G24K4/V valve is compatible with various hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR types. It also features FKM seals that enhance its durability and resistance to harsh conditions. With its robust construction and comprehensive specifications tailored for demanding applications, this Bosch Rexroth valve represents a reliable choice for controlling fluid dynamics in industrial settings.

Type 4WRE...-2X/...
The 4/2 and 4/3 proportional directional valves are designed as direct operated devices in plate design. Operation by means of proportional solenoids with central thread and detachable coil. The solenoids are controlled by external electronics.
Set-up:
The valve basically consists of:
Housing (1) with connection surface Control spool (2) with compression springs (3 and 4) and spring plates (5 and 6) Solenoids (7 and 8) with central thread Position transducer (9)Function:
With de-energized solenoids (7 and 8), central position of the control spool (2) due to compression springs (3 and 4) between the spring plates (5 and 6) Direct actuation of the control spool (2) by the control of one proportional solenoid, e. g. solenoid "b" (8) Control spool (2) is moved to the left in proportion to the electrical input signal Connection from P to A and B to T via orifice-type cross-sections with progressive flow characteristics Switching off of the solenoid (8) Control spool (2) is returned to the central position by the compression spring (3)In the de-energized state, the control spool (2) is held in a mechanical central position by the return spring of the solenoids. With control spool symbol "V", this position does not correspond to the hydraulic central position! When the electric valve control loop is closed, the control spool is positioned in the hydraulic central position.
Important notice:
The PG fitting (11) must not be opened. Mechanical adjustment of the adjustment nut located below is prohibited and damages the valve!
Valve with two spool positions: (Type 4WRE…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 “a” (7). Instead of the 2nd proportional solenoid, a plug screw (10) is installed.
Notice:
Due to the design principle, internal leakage which may increase over the life cycle is inherent to the valves.
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.
