The Bosch Rexroth 4WRAE6EA07-2X/G24N9K31/A1V (R900966133) is a high-performance direct operated proportional directional valve with a plate design and is used for controlling the direction and magnitude of fluid flow. This valve operates using proportional solenoids with a central thread and detachable coil, which are governed by integrated electronics. It consists of a housing with a connection surface, a control spool balanced by compression springs, and solenoids that act directly on the spool.
The functionality of this valve allows for precise movement control: when solenoids are de-energized, the control spool remains in its central position due to the compression springs. Upon energization of one proportional solenoid, the spool moves proportionally to the electrical input signal, enabling flow from P to A and B to T through orifice-type cross-sections designed for progressive flow characteristics. When the solenoid is switched off, the control spool returns to its central position via spring force.
This particular model features two spool positions (type WRA...A...), where it operates with only one solenoid and either a plug screw or cover in place of the second solenoid depending on installation requirements. It's important to note that precautions must be taken to ensure that the tank line does not run empty; if necessary, a preload valve with approximately 5 bar pressure should be installed.
Designed for subplate mounting according to ISO standards, this Bosch Rexroth valve has specifications including size 6, component series X (10), maximum operating pressure of 350 bar, and maximum flow of 60 l/min. Its application allows for seamless integration into various hydraulic systems where precise flow control is critical without requiring electrical position feedback.

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
