The Bosch Rexroth 4WRAE6E15-2X/G24N9K31/F1V (R900947059) is a high-performance proportional directional valve designed for precise control of hydraulic flow and direction. This direct-operated valve is constructed for plate design mounting and operates using proportional solenoids with a central thread and a detachable coil, which are controlled by integrated electronics. The valve's housing includes a connection surface, and it features a control spool balanced by compression springs, ensuring reliable operation.
The 4WRAE6E15-2X/G24N9K31/F1V excels in applications requiring the control of the direction and magnitude of flow without electrical position feedback. It is particularly suitable for subplate mounting with its porting pattern conforming to ISO standards. The spring-centered control spool facilitates smooth transitions between positions, returning to the central position when solenoids are de-energized.
This model has two spool positions, type WRA...A..., where one solenoid actuates the valve while the other side has either a plug screw or cover depending on size specifications. It ensures progressive flow characteristics through orifice-type cross-sections when transitioning from P to A and B to T ports.
For optimal performance, the tank line must not be allowed to run empty, and under certain installation conditions, a preload valve with approximately 5 bar preload pressure should be installed. The 4WRAE6E15-2X/G24N9K31/F1V can withstand a maximum operating pressure of 350 bar and can handle a maximum flow of up to 15 liters per minute, making it robust for various hydraulic applications where precise flow control is essential.

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 via integrated electronics.
Set-up:
The valve basically consists of:
Housing (1) with connection surface Control spool (2) with compression springs (3 and 4) Solenoids (5 and 6) with central thread Integrated electronics (7)Function:
With de-energized solenoids (5 and 6), central position of the control spool (2) due to compression springs (3 and 4) Direct actuation of the control spool (2) by energization of one proportional solenoid, e. g. energization of solenoid "b" (6) 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 (6) Control spool (2) is returned to the central position by the compression spring (3)
Valve with two spool positions (type 4WRA...A...):
The function of this valve version basically corresponds to the valve with three spool positions. This 2 spool position valve is, however, only equipped with solenoid “a”. Instead of the 2nd proportional solenoid, there is a plug screw (8.1) with NG 6 or a cover (8.2) with NG10.
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.

Command value:
Positive command value (0...10 V or 12...20 mA) at D and reference potential at E result in flow from P → A and B → T.
Negative command value (0...-10 V or 12...4 mA) at D and reference potential at E result in flow from P → B and A → T.
With valves with solenoid on side “a” (control spool variant EA and WA), a positive command value at D and reference potential at E (NG6: 4...20 mA and NG10: 12...20 mA) result in flow from P → B and A → T.
Connection cable: Recommendation:
up to 25 m cable length type LiYCY 5 x 0.75 mm²
up to 50 m cable length type LiYCY 5 x 1.0 mm²
External diameter 6.5 … 11 mm
Connect shield on PE only on the supply side
