4WRKE…30 Electro-hydraulicProportional Directional Valve
4WRKE…30 Electro-Hydraulic Proportional Directional Valve is designed for precise control of oil flow direction and flow rate in hydraulic systems. It combines proportional solenoid control with hydraulic pilot operation, providing high flow capacity, smooth spool movement, and stable response. This valve is suitable for heavy-duty hydraulic equipment, industrial machinery, hydraulic presses, injection molding machines, and automation systems that require accurate motion control and reliable performance.
