The Bosch Rexroth 4WRA6WA15-2X/G24K4/V (R900954059) is a high-performance industrial hydraulic valve designed for reliable control of oil flow direction in accordance with its WA spool symbol. This direct-actuated spool valve is characterized by its size, and it is built for electrical actuation with external electronics. It features a maximum pressure capability and utilizes an electrical connection that conforms to the EN standard with a Connector pole PE.
The 4WRA6WA15-2X/G24K4/V valve operates with a maximum flow rate and is designed for subplate mounting, adhering to the NFPA T.. R D SizeCETOP D and ISO connection diagrams. The nominal flow rate for this valve is specified, and it requires a supply voltage of VDC to function properly. The number of switching positions ensures versatility in operation, while the weight of the unit makes it suitable for various applications.
Equipped with FKM seals, this Bosch Rexroth valve can handle a variety of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. Its design features include housing with a connection surface and control spool accompanied by compression springs. The solenoids are centrally threaded and come with detachable coils for ease of maintenance.
This model operates without electrical position feedback but requires external electronics to control the direction and magnitude of fluid flow. It has been engineered for straightforward operation via proportional solenoids and offers spring-centered control spool functionality. In terms of setup, the 4WRA6WA15-2X/G24K4/V boasts two spool positions type WRA...A..., differing from three-position models by having only one solenoid plus either a plug screw or cover depending on size NG.
For optimal performance, it's important to ensure that the tank line does not run empty during operation; if necessary due to installation conditions, a preload valve with an approximate preload pressure should be installed.

Size 6, symbol WA, 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: 1.420 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.
