What is 4WEH Series Directional Valves?

1. Introduction to 4WEH series Directional Valves

4WEH Series Directional Valves play a vital role in hydraulic systems, controlling the start, stop and direction of fluid flow. These valves are commonly used in a variety of industrial applications, providing efficient and reliable performance.

2. Basic concepts

2.1 Definition

The 4WEH series consists of pilot operated spool valves. These valves utilize an oil-immersed Solenoid Valve to drive the Pilot Valve's control spool to determine the flow path. By adjusting pilot flow, the main stage piston moves, allowing precise flow direction control.

2.2 Basic principles and structure

Pilot operation: The pilot valve is operated by an oil-immersed solenoid valve, which positions the control spool.

Spool Types: This series offers a variety of spool types, allowing customization for specific applications.

Interchangeability: These valves comply with ISO 4401 standards and are easily interchangeable.
