4WRA(E)…20 Solenoid Proportional Directional Valve
4WRA(E)…20 Solenoid Proportional Directional Valve is designed for accurate direction and flow control in hydraulic systems. It uses proportional solenoid control to adjust spool movement according to electrical input signals, providing smooth speed regulation, stable operation, and precise motion control. With reliable performance and a compact structure, this valve is widely used in industrial machinery, hydraulic presses, automation equipment, and other hydraulic systems requiring proportional directional control.
