The Bosch Rexroth 4WRE6E1-16-2X/G24K4/V (R900954093) is a high-performance proportional directional valve designed for precise control of flow direction and size in hydraulic systems. This direct-operated valve is equipped with electrical position feedback and requires external electronics for operation. The robust construction features proportional solenoids with a central thread and a detachable coil, facilitating easy maintenance and serviceability.
This valve is tailored for subplate mounting and adheres to the porting pattern specified by ISO standards, ensuring compatibility with a wide range of systems. The spring-centered control spool guarantees reliable neutral positioning when the solenoids are deenergized, while the progressive flow characteristics enable smooth operation when actuated. With its size 6 form factor and component series X, it can withstand a maximum operating pressure of up to 350 bar and can handle maximum flow rates of up to 60 liters per minute.
Designed primarily for applications requiring precise control in fluid power systems, the Bosch Rexroth 4WRE6E1-16-2X/G24K4/V ensures efficient performance with its advanced design that includes features such as a position transducer for accurate spool positioning. Users should be aware that internal leakage may occur due to its design principle, which could increase over the valve's lifecycle. Additionally, precautions must be taken to prevent the tank line from running empty, potentially necessitating the installation of a preload valve if certain installation conditions are met.
Overall, this Bosch Rexroth proportional directional valve represents a sophisticated solution for industrial hydraulics where precision and reliability are paramount.

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.
