The Bosch Rexroth 4WRAE10EA30-2X/G24K31/A1V (R900954085) 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 actuation. The valve operates at a maximum pressure and offers a nominal flow rate, ensuring efficient performance in various hydraulic applications. With its electrical connection described as a connector pole PE according to EN, the 4WRAE10EA30-2X/G24K31/A1V provides secure and stable connectivity. It has multiple ports for versatile use and supports subplate mounting with a connection diagram conforming to NFPA T.. R D SizeCETOP D and ISO standards. The supply voltage required for operation is VDC, which powers the integrated electronics that facilitate the valve's functionality. The proportional directional valves are designed with two spool positions for effective management of flow paths. These valves are spring-centered, ensuring that the control spool returns to its central position when solenoids are de-energized. The robust construction includes FKM seals that offer compatibility with various hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. In terms of connectivity options, this model provides analog command value input ranging from V to ensure precise control over the hydraulic system it is integrated into. Its compact size and CETOP standard dimensions make it suitable for a wide range of industrial applications where space efficiency and reliable performance are critical. Overall, the Bosch Rexroth 4WRAE10EA30-2X/G24K31/A1V valve represents a sophisticated solution for controlling fluid dynamics in complex hydraulic systems where precision and reliability are paramount.
Size 10, symbol EA, 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: 4.7 kg
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.
