Ball Valve

The ball valve has a 90 degree rotation action, and the plug body is a ball with a circular through hole or channel passing through its axis. Ball valves are mainly used in pipelines to cut off, distribute, and change the flow direction of the medium. They can be tightly closed with only 90 degrees of rotation and a small rotational torque.

Butterfly Valve

Butterfly valves have simple structure, small volume, and light weight. In the cylindrical channel of the butterfly valve body, the butterfly plate rotates around the axis, with a rotation angle between 0 ° and 90 °, which can play a role in flow regulation. When the butterfly plate rotates to 90 °, the valve reaches its maximum opening.
