The 4WEH16E electro-hydraulic directional valve represents a sophisticated fluid control solution engineered for industrial hydraulic systems operating under demanding conditions. Combining electromagnetic pilot control with hydraulic actuation technology, this valve enables precise fluid circuit switching through electrical signals, making it suitable for automation requirements in construction machinery, metallurgical equipment, and marine hydraulic systems.
Manufactured from high-strength alloy casting with precision machining, the valve body ensures smooth internal flow channels and reliable sealing performance. Its modular construction allows multiple neutral position configurations, offering flexible spool transition options tailored to system specifications. The main spool undergoes specialized surface treatment and incorporates precision guidance mechanisms, significantly reducing operational friction while maintaining consistent shifting responsiveness under pressure fluctuations.
Designed for broad media compatibility, the valve operates effectively with hydraulic oils ranging from ISO VG32 to VG68 viscosity grades, functioning reliably within ambient temperatures from -20℃ to +80℃. The fully enclosed electromagnetic pilot unit provides water-resistant protection meeting general industrial standards, demonstrating excellent resistance to vibration and contamination. Compact dimensions facilitate installation in confined spaces, while standardized flange connections at fluid ports support versatile piping configurations.
In practical applications, the valve exhibits outstanding pressure stability with maximum working pressure of 350 bar and transient peak pressure resistance up to 420 bar. The optimized internal damping structure effectively mitigates hydraulic shock, complemented by adjustable throttling devices that allow operators to fine-tune shifting speeds according to operational requirements. Each unit undergoes rigorous quality verification processes to ensure long-term performance consistency in industrial hydraulic circuits.
