The Bosch Rexroth 4WRE10E50-2X/G24K4/V (R900954101) is a high-performance, direct-actuated proportional directional valve designed for industrial hydraulic systems. This valve features a spool valve with symbol E and utilizes external amplifier technology to ensure precise control of oil flow direction. It boasts a maximum pressure capacity and includes an electrical connection with a connector pole PE conforming to EN standards. The 4WRE10E50-2X/G24K4/V is equipped with integrated electronics for streamlined operation and is actuated electrically with the necessary external electronics. This model has a subplate mounting type of connection, following the NFPA T.. R D SizeCETOP D and ISO connection diagrams, which facilitates easy installation and maintenance. Designed for versatility, it supports various hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, HFDR types and comes equipped with FKM seals to withstand different operating conditions. In terms of construction, the valve comprises a housing that provides the connection surface and a control spool that is maintained in position by compression springs and spring plates. The solenoids attached come with central threads for secure fitting and are accompanied by a position transducer to relay precise spool positioning feedback. The 4WRE10E50-2X/G24K4/V model operates effectively by shifting its control spool in response to electrical input signals which directly influence flow rates. It also features spring-centered control spools that return to their mechanical central position when deenergized. This particular model is designed for applications that require reliable performance under substantial operating pressures up to bar and can handle maximum flow rates of l/min. Its design ensures dependable operation across various industrial applications demanding accurate hydraulic flow control.

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.
