The Bosch Rexroth 4WRAE6W30-2X/G24N9K31/A1V (R900900987) is a high-performance industrial hydraulic valve designed for reliable control of oil flow direction based on the hydraulic symbol "W". This direct actuated spool valve features integrated electronics that facilitate the electrical actuation of the valve with a supply voltage of 24 VDC. It is equipped with a concealed manual override and auxiliary actuation for enhanced operational flexibility. The valve is characterized by its subplate mounting connection, conforming to ISO standards, and an NFPA T3.5.1 R2 D03 size CETOP D pattern.
With a nominal flow capacity and maximum pressure rating, the 4WRAE6W30-2X/G24N9K31/A1V valve ensures precise control over flow rates in hydraulic systems. Its connectivity options include an analog command value input ranging from 0 to 10 V for seamless integration into various control circuits. The valve's construction includes FKM seals making it suitable for use with a wide range of hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR.
The robust design includes a housing with connection surface and control spool with compression springs ensuring stable operation. The proportional solenoids come with central thread and detachable coil for ease of maintenance. In its default state with deenergized solenoids, the control spool maintains its central position due to the compression springs; when energized proportionally to the input signal strength, it actuates to adjust the flow accordingly.
This Bosch Rexroth proportional directional valve is ideally suited for applications requiring precise control without electrical position feedback. Its spring-centered control spool returns it to neutral when de-energized ensuring safety and reliability in system operations. With its advanced features and robust construction, this valve represents a dependable solution for sophisticated hydraulic system requirements.

Size 6, symbol W, electrical with integrated electronics, 24 V DC
Industrial hydraulic valve in a high performance range, reliable control of oil flow direction according to hydraulic symbol.
Unpacked Weight: 2.2 kg
Direct operated proportional directional valve, without electrical position feedback, with integrated electronics (OBE) Control of the direction and magnitude of a flow Operation by means of proportional solenoids with central thread and detachable coil For subplate mounting: Porting pattern according to ISO 4401 Spring-centered control spool
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
