The Bosch Rexroth 4WRA10E60-2X/G24N9K4/V (R900902097) is a high-performance industrial hydraulic valve designed for reliable control of oil flow direction in accordance with its spool symbol, Symbol E. This direct-actuated spool valve features a concealed manual override and auxiliary actuation, ensuring versatility and security in operation. It operates electrically with external electronics, requiring a supply voltage of 24 VDC.
The valve is engineered for subplate mounting with a CETOP D size connection surface and conforms to ISO connection diagram standards. It boasts a maximum pressure capacity and can handle a nominal flow rate efficiently. The number of ports and switching positions are optimized for diverse hydraulic applications.
Equipped with FKM seals, the 4WRA10E60-2X/G24N9K4/V is compatible with an array of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR types. Its robust construction ensures that it can perform under demanding conditions while maintaining precise control over flow direction.
The valve features solenoids with central threads and detachable coils that are controlled by external electronics. In its default state—with deenergized solenoids—the control spool is held in the central position by compression springs. When activated by an electric input signal, the solenoid proportionally displaces the control spool to adjust the flow from P to A and B to T through orifice-type cross-sections with progressive characteristics.
For maintenance purposes or during certain operational modes, users will appreciate the inclusion of a concealed manual override function. The design consideration for preventing the tank line from running empty indicates that this valve may require additional components such as a preload valve under specific installation conditions.
Overall, the Bosch Rexroth 4WRA10E60-2X/G24N9K4/V offers precise control for hydraulic systems without electrical position feedback but with dependable external electronic management.

Size 10, symbol E, electrical with external electronics, 24 V DC
Industrial hydraulic valve in a high performance range, reliable control of oil flow direction according to hydraulic symbol.
Unpacked Weight: 5.96 kg
Direct operated proportional directional valve without electrical position feedback, with external electronics 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 by external control 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 threadFunction:
With de-energized solenoids (5 and 6), central position of the control spool (2) by compression springs (3 and 4) Direct operation of the control spool (2) by energization a proportional solenoid, e.g. control of solenoid "b" (6) Displacement of the control spool (2) to the left, proportionally to the electric input signal Connection from P to A and B to T via orifice-type cross-sections with progressive flow characteristics Switching off the solenoid (6) The compression spring (3) brings the control spool (2) back into the central position
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.
