The Bosch Rexroth 4WRAE10EA60-2X/G24K31/A1V (R900954086) is a high-performance industrial hydraulic valve designed for reliable control of oil flow direction. This direct-actuated spool valve features an EA spool symbol and is equipped with integrated electronics for precise electrical actuation. The valve operates with a maximum pressure capacity and offers a nominal flow rate, ensuring efficient fluid management in hydraulic systems.
With its subplate mounting design conforming to ISO standards, the 4WRAE10EA60-2X/G24K31/A1V is suitable for various applications requiring robust performance and easy installation. The valve's electrical connection is facilitated through a Connector pole PE according to EN, which simplifies integration into existing systems. It can handle a variety of hydraulic fluids, including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR.
The valve's construction includes a durable housing with a control spool balanced by compression springs and operated by proportional solenoids featuring a central thread and detachable coil. The integrated electronics allow for smooth operation by converting electrical input signals into mechanical movement of the spool. This results in precise control over the connection from P to A and B to T channels within the valve.
Designed for versatility, the Bosch Rexroth 4WRAE10EA60-2X/G24K31/A1V offers analog connectivity with command values ranging from 0 to 10 V. Equipped with FKM seals for enhanced durability against harsh fluids and environments, this valve maintains its integrity over extended periods of use. Its spring-centered control spool ensures that the system returns to neutral when de-energized, providing safety and stability in operation.

Industrial hydraulic valve in a high performance range, reliable control of oil flow direction according to hydraulic symbol.
Unpacked Weight: 4.660 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
