1. Leave the position where the valve handle rotates.
2. Cannot be used for throttling.
3 The ball valve with the transmission mechanism should be installed upright.

The working principle of the three-way ball valve is to make the valve unblocked or blocked by rotating the valve. The ball valve switch is light, small in size, can be made into a large diameter, reliable sealing, simple structure, convenient maintenance, the sealing surface and the spherical surface are often closed, and are not easily eroded by the medium, and are widely used in various industries.
The three-way ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline.
The three-way ball valve is a relatively new type of ball valve. It has some advantages unique to its own structure, such as no friction on the switch, the seal is not easy to wear, and the opening and closing torque is small. This reduces the size of the fitted actuator. Equipped with a multi-turn electric actuator, it can realize the adjustment and strict shut-off of the medium. It is widely used in petroleum, chemical industry, urban water supply and drainage and other working conditions that require strict cut-off.
