The Bosch Rexroth 4WRA10W60-2X/G24K4/V (R900954065) is a high-performance industrial hydraulic valve that offers reliable control of oil flow direction in accordance with its spool symbol 'Symbol W'. This direct actuated spool valve is designed for subplate mounting with a connection pattern conforming to ISO standards. The valve is characterized by its size 10, and it operates under a maximum pressure of 315 bar with a nominal flow rate.
Equipped with two proportional solenoids featuring central threads and detachable coils, the 4WRA10W60-2X/G24K4/V valve's operation is controlled by external electronics. These solenoids are responsible for the precise actuation of the control spool, allowing for adjustments proportional to the electric input signal. The electrical connection for this valve is facilitated through a Connector pole PE according to EN standards.
The spring-centered control spool ensures that the device returns to its neutral position when de-energized, maintaining stability and safety in the system. The valve's design includes two spool positions, type WRA...A..., which correspond to the functionality of three-position valves but are equipped with only one solenoid and a plug screw or cover for the second position.
The hydraulic fluids compatible with this valve range from HL through HFDU and HFDR types, while FKM seals provide durability against these various media. This versatility makes it suitable for diverse hydraulic applications where precise flow direction and magnitude control are required. The Bosch Rexroth 4WRA10W60-2X/G24K4/V also emphasizes user safety by noting that the tank line must not run empty, recommending a preload valve if necessary under certain installation conditions.

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.
