The 4WEH16D electro-hydraulic directional valve is an intelligent control component specifically developed for industrial hydraulic systems. Combining solenoid actuation with hydraulic pilot control, this valve achieves precise fluid flow direction switching, making it suitable for diverse hydraulic circuit control requirements in various industrial applications.
Constructed with high-strength alloy materials through precision casting, the valve body features optimized internal flow channels that minimize pressure loss while enhancing fluid transmission efficiency. The main spool undergoes specialized surface hardening treatment and incorporates multi-stage sealing structures, ensuring both smooth directional switching and improved wear resistance. The integrated electromagnetic pilot control unit includes multiple protective mechanisms to maintain stable signal transmission under voltage fluctuations and transient overload conditions.
This four-position five-way valve enables flexible workflow switching control in hydraulic systems. With a rated operating pressure range of 16MPa to 31.5MPa, it is compatible with standard hydraulic oils within ISO VG32-VG68 viscosity grades. The modular design allows for stackable installation, facilitating integration with various hydraulic valve groups. Multiple coil voltage options including DC12V/24V and AC110V/220V are available to accommodate different operational requirements.
In industrial applications, the 4WEH16D demonstrates excellent performance in pressure control systems for metallurgical equipment, actuator movement coordination in construction machinery, and mold clamping systems for injection molding machines. Its rapid response characteristics meet high-frequency switching demands, while the integrated cushioning mechanism effectively reduces hydraulic shock, thereby extending the service life of connected components. The valve s compact dimensions and standardized interface design simplify installation and maintenance procedures across different equipment platforms.
