Product Introduction of Piston type Electro hydraulic Valve

1. Overview

Piston type electro-hydraulic valve is a device that controls fluid flow in hydraulic systems through electrical signals. It is widely used in industrial automation, engineering machinery, and other fields, and has the characteristics of fast response, high control accuracy, and strong reliability.

2. Working principle

Electrical signal control: By energizing an electromagnetic coil to generate a magnetic field, the piston is driven to move.

Piston movement: The movement of the piston changes the position of the valve core, thereby controlling the direction and flow rate of hydraulic oil.

Hydraulic control: By changing the position of the valve core, precise control of hydraulic actuators is achieved.

3. Main structure

Electromagnetic coil: After being powered on, it generates a magnetic field to drive the piston.

Piston: moves under the action of a magnetic field, driving the valve core.

Valve core: controls the flow of hydraulic oil.

Valve body: accommodates various components to ensure sealing and fluid passage.

4. Product Features

High response speed: Electromagnetic drive, rapid response.

Precise control: can accurately adjust flow and direction.
