The Bosch Rexroth 4WRA10W30-2X/G24K4/V (R900577424) is a high-performance industrial hydraulic valve that provides reliable control over the direction of oil flow. This direct actuated spool valve features a spool symbol W, indicating its configuration, and is designed for electrical actuation with external electronics. The valve operates with a maximum pressure capacity and utilizes an electrical connection with a connector pole PE according to EN standards.
With its subplate mounting design, the valve adheres to the ISO connection diagram and NFPA T.. R D SizeCETOP D standards, ensuring compatibility with various hydraulic systems. It offers a nominal flow rate and is capable of handling multiple types of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. The seals are made from FKM material to ensure durability and resistance against harsh fluids.
The 4WRA10W30-2X/G24K4/V valve is characterized by its two spool positions type WRA...A..., which allows for precise control of flow magnitude without the need for electrical position feedback. It operates efficiently on a supply voltage of VDC and features spring-centered control spools for reliable return to neutral position. This Bosch Rexroth valve is ideal for applications requiring exacting flow control in complex hydraulic systems.
Its robust design includes housing with a connection surface, control spool with compression springs, and solenoids with central thread. The valve ensures smooth transition from P to A and B to T connections through orifice-type cross-sections that offer progressive flow characteristics. When not energized, the compression springs maintain the spool in the central position; upon energization of the solenoid(s), the spool moves proportionally to the electric input signal.
Designed for ease of installation and maintenance-free operation within specified conditions—such as ensuring that tank lines do not run empty—the Bosch Rexroth 4WRA10W30-2X/G24K4/V stands out as an essential component in advanced industrial hydraulic systems.

Industrial hydraulic valve in a high performance range, reliable control of oil flow direction according to hydraulic symbol.
Unpacked Weight: 6.02 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.
