The Bosch Rexroth 4WRA6E30-2X/G24N9K4/V (R900902940) is a high-performance industrial hydraulic valve renowned for its reliable control over the direction of oil flow according to the hydraulic symbol E. This direct-actuated spool valve comes equipped with a concealed manual override and auxiliary actuation, ensuring precise operation under various conditions. Its design features a spool valve with a direct operation that is actuated by proportional solenoids which are centrally threaded and come with detachable coils. These solenoids are externally controlled by separate control electronics.
The 4WRA6E30-2X/G24N9K4/V is designed for subplate mounting and follows the porting pattern according to ISO standards, making it versatile for integration into various systems. It has a maximum operating pressure of bar and can manage a maximum flow rate of l/min, showcasing its capability to handle substantial hydraulic demands. The valve's size and component series X indicate its compatibility with different setups within its specified range.
Furthermore, this model features an electrical connection described as a connector pole PE in accordance with EN standards, ensuring secure and reliable electrical interfacing. The type of actuation is electrical with external electronics, which provides precise control over the valve's functions. It supports a supply voltage of VDC and is designed for use with numerous types of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, HFDR while utilizing FKM seals to maintain integrity under various operating conditions.
In summary, the Bosch Rexroth 4WRA6E30-2X/G24N9K4/V valve offers robust performance for controlling oil flow direction in industrial hydraulic systems. With its advanced features such as concealed overrides and external electronic actuation combined with high-pressure and flow capabilities, it stands as an essential component for sophisticated hydraulic applications requiring precise directional control.

Size 6, symbol E, 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: 1.96 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.
