The Bosch Rexroth 4WRAE6M30-2X/G24N9K31/A1V (R900935958) is a high-performance proportional directional valve designed for direct operation and subplate mounting, with a porting pattern according to ISO standards. This valve is characterized by its direct actuation through proportional solenoids that feature a central thread and detachable coil, which are governed by integrated electronics. The housing of the valve includes a control spool balanced by compression springs, ensuring precise control of hydraulic flow.
In terms of functionality, the 4WRAE6M30-2X/G24N9K31/A1V valve allows for the meticulous management of both the direction and magnitude of fluid flow without electrical position feedback. When the solenoids are de-energized, the control spool remains in a central position due to the compression springs. Upon energization of one solenoid, the control spool shifts proportionally to the electrical input signal, enabling progressive flow characteristics between ports.
This specific model is equipped with two spool positions (type WRA...A...), utilizing only one proportional solenoid and substituting the second solenoid with either a plug screw or cover, depending on installation needs. It is imperative to note that precautions must be taken to prevent the tank line from running dry; if necessary, a preload valve with an approximate preload pressure of 5 bar should be installed.
The Bosch Rexroth 4WRAE6M30-2X/G24N9K31/A1V valve boasts impressive technical specifications including a size 6 design, component series X (10), maximum operating pressure of 315 bar, and maximum flow rate capability reaching up to 60 liters per minute. This product offers reliable performance in controlling hydraulic systems where precise flow regulation is critical.

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
