The Bosch Rexroth 4WRAE10W1-60-2X/G24N9K31/A1V (R900936006) is a high-performance proportional directional valve, expertly designed for precise control of flow direction and magnitude in hydraulic systems. This direct-operated valve is constructed for plate design mounting and features a robust housing that contains the control spool, which is balanced by compression springs. The operation of this valve is facilitated by proportional solenoids with a central thread and detachable coil, which are regulated through integrated electronics for seamless performance. The 4WRAE10W1-60-2X/G24N9K31/A1V valve boasts a spring-centered control spool that returns to its neutral position when the solenoids are deenergized, ensuring stable and reliable operation. When one of the solenoids is activated, it directly actuates the control spool in proportion to the electrical input signal, allowing for precise adjustments to be made to the hydraulic flow. This model features orifice-type cross-sections with progressive flow characteristics that enable smooth transitions from P to A and B to T ports. This particular model of the valve comes with two spool positions (type WRA...A...), where only one solenoid is utilized for operation, while the second position is replaced by either a plug screw or cover depending on the size requirement (NG6 or NG10). It's important to note that precautions must be taken to ensure that the tank line does not run empty during operation, and if necessary, a preload valve with approximately 5 bar pressure should be installed. With an impressive maximum operating pressure of 315 bar and a maximum flow rate of 60 liters per minute, this Bosch Rexroth proportional directional valve without electrical position feedback but with integrated electronics OBE is ideal for subplate mounting with porting pattern according to ISO standards. It's well-suited for applications requiring meticulous control over hydraulic system flow within various engineering contexts.

Direct operated proportional directional valve, without electrical position feedback, with integrated electronics (OBE) 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 via integrated 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 Integrated electronics (7)

Function:

With de-energized solenoids (5 and 6), central position of the control spool (2) due to compression springs (3 and 4) Direct actuation of the control spool (2) by energization of one proportional solenoid, e. g. energization of solenoid "b" (6) Control spool (2) is moved to the left in proportion to the electrical input signal Connection from P to A and B to T via orifice-type cross-sections with progressive flow characteristics Switching off of the solenoid (6) Control spool (2) is returned to the central position by the compression spring (3)

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.
