4WE Series Hydraulic Directional Solenoid Valves

Features:

1、Easy installation and maintenance
2、High reliability and long service life
3、Precise steering control

The 4WE series hydraulic valves feature a core structure of cast iron valve bodies and alloy steel valve spools. Cast iron offers good machine ability for creating precise internal galleries and port connections, and it effectively dampens vibrations transmitted from the hydraulic system. The valve spool, the moving core component, is made from alloy steel that is hardened and ground to a fine finish. Over time, forming the basis for its performance features.

The 4WE series directional solenoid valves are designed with standardized porting and mounting interfaces, conforming to common hydraulic manifold standards. This allows for direct integration into system valve blocks without the need for complex adapters or brackets. External connections for electrical solenoids are typically made via plug-in connectors with protective covers, simplifying wiring and troubleshooting.

The hardened alloy steel valve spools work in conjunction with precisely machined cast iron body bores, providing a wear-resistant sliding pair that maintains sealing integrity over millions of cycles. The solenoids are engineered with encapsulated coils resistant to moisture and vibration, and are often available with multiple protection classes (e.g., IP65). Internal damping chambers and optimized flow paths help to reduce hydraulic shock and cavitation, which are primary causes of wear and failure in valve components.

Precise control is facilitated by the valve's spool design and actuation response. The spools are machined to tight tolerances, with carefully profiled notches (metering edges) that regulate the flow rate and direction with a high degree of repeatability. The direct-acting solenoid mechanism provides a swift and definitive shift between positions, ensuring consistent response times.
