Structural principle of two position four way directional valve

The two position four directional valve has two valve ports and four valve positions. Its structure consists of a valve body, a valve core, and a handle. The valve body is composed of inlet, outlet, oil circuit and other components, and the valve core is composed of control chamber, spring, seal and other components. The handle can manually or electrically control the movement of the valve core in the valve body.

 

In the working system, the electromagnet receives an electrical signal to push the valve core to reverse direction and change the direction of medium flow. After the electrical signal disappears, the valve core automatically resets through the spring to achieve automatic control, and is equipped with a manual device. The two position four directional valve changes the direction and flow direction of hydraulic oil flow in the hydraulic system by controlling the movement of the valve core in the valve body. When the valve core moves from one position to another, it can guide hydraulic oil flow to different inlet and outlet ports.
