The Bosch Rexroth 4WRA10WA60-2X/G24N9K4/V (R900935623) is a high-performance proportional directional valve designed for subplate mounting with a porting pattern according to ISO standards. This direct operated plate design valve is equipped with proportional solenoids that feature a central thread and detachable coil, which are controlled by external electronics. The valve's operation is characterized by its ability to control the direction and magnitude of fluid flow in hydraulic systems without electrical position feedback. The setup of the 4WRA10WA60-2X/G24N9K4/V includes a housing with connection surfaces, a control spool balanced by compression springs, and solenoids for actuation. In its default state, the control spool is held in the central position by the springs. When energized, one of the solenoids displaces the control spool proportionally to the electric input signal, allowing for precise flow control from P to A and B to T through orifice-type cross-sections with progressive flow characteristics. This particular model has two spool positions and is fitted with only one solenoid (solenoid a), while the second position is replaced by either a plug screw or cover depending on whether it’s NG6 or NG10. It provides reliable performance with a maximum operating pressure of 315 bar and can handle maximum flow rates up to 60 l/min. For proper functioning, it's important to ensure that the tank line does not run empty; if necessary, based on installation conditions, a preload valve (with approximately 10 bar preload pressure) should be installed. The Bosch Rexroth 4WRA10WA60-2X/G24N9K4/V offers precision control in hydraulic applications where accurate manipulation of flow is required without feedback on valve position.

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 thread

Function:

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.
