Product details

WEH/WH Electro-Hydraulic Directional Control Valve, or Hydraulic Directional Control Valve, refers specifically to a type of valve that uses electromagnetic or hydraulic pilot control to switch the direction of fluid flow in a hydraulic system. Here are some specific details:

1. Structure and Principle:

• WEH/WH electro-hydraulic directional control valves are slide valve-type directional control valves that use solenoid valves as pilot controls.

• They consist of a main valve body, a main valve spool, one or two return springs, and a pilot solenoid valve with one or two electromagnets.

2. Functions and Applications:

• These valves are used to control the on-off state and flow direction of hydraulic fluid.

• They are widely used in hydraulic systems of various machinery and equipment, such as excavators, loaders, road rollers, agricultural machinery, marine machinery, and more, to achieve functions such as starting, stopping, reversing, and speed regulation of hydraulic cylinders or hydraulic motors.

3. Optional Features and Accessories:

• The solenoid valve for pilot control can be wet-type AC or DC.

• They may come with or without fault check buttons, with separate or centralized electrical connections.

• The main valve can adopt spring centering and spring return, or hydraulic centering and hydraulic return to the initial position.

• Optional features may include a directional change time adjuster, a main valve stroke limiter, a pre-pressure valve installable in the main valve, an insertable damper, and a pressure reducing valve installable when the working pressure exceeds 25 MPa.

4. Installation and Connection:

• WEH/WH electro-hydraulic directional control valves adopt plate connection, and their connection dimensions comply with DIN2430 and ISO4401 standards.

In summary, WEH/WH Electro-Hydraulic Directional Control Valves, or Hydraulic Directional Control Valves, are important components in hydraulic systems. Their precise control of fluid direction contributes to the efficient and stable operation of various machinery and equipment.
