Functional description, sectional drawing
4WRA(E)... L2X proportional directional valves control the flow and direction of liquid through the proportional solenoid actuating the spool, and the proportional solenoid can be driven by an external amplifier (4WRA...L2X) or a built-in amplifier (4WRAE...L2X). The proportional solenoid can be operated by an external amplifier (4WRA...L2X) or a built-in amplifier (4WRAE...L2X). L2X).
The valve consists mainly of a valve body, a centering spring, a spool, a threaded proportional solenoid, and an optional built-in amplifier. When the solenoid is not energized, the centering spring keeps the control spool in the neutral position, if the right solenoid "b" is energized, the solenoid pushes the spool ( to move to the left, the spool displacement is proportional to the input signal, the P-port to the A-port, the B-port to the T-port is communicated through the spool and the body of the valve formed by the gradual throttling port. If the left solenoid "a" is energized, port P to port B and port A to port T are connected through the gradual throttling port.
