Ball valve Application

Ball valve, opening and closing parts (ball) driven by the valve stem, and around the ball valve axis for rotary movement of the valve. Can be used for fluid regulation and control, Ball valves are generally installed horizontally in the pipeline

 

Ball valves classification

By structure:

Floating ball valve, fixed ball valve, V-ball valve, three-way ball valve, manual ball valve, pneumatic ball valve, electric ball valve, welding ball valve and so on.

 

Ball valve characteristics

①Low fluid resistance and small volume.

②Tight and reliable, good seal.

③Convenient operation, quick opening and closing.

④Simple structure, convenient maintenance.

⑤ Wide range of application, high vacuum or high pressure can be applied.
