Ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball (called a "floating ball") to control flow through it. It is open when the ball's hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle. The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve's status.

Ball valves are durable, performing well after many cycles, and reliable, closing securely even after long periods of disuse. These qualities make them an excellent choice for shutoff applications, where they are often preferred to gate and globe valves, but they lack their fine control in throttling applications.

function of ball valve

The main function of the ball valve is to cut off the flow, distribute the velocity of flow and change the direction of flow, it can rotate 90 degrees.Ball valves have many functions. They can also be used as switches.In China, ball valves are widely used in petroleum refining, long-distance pipeline, chemical industry, paper making, pharmaceutical, water conservancy, electric power, municipal, steel and other industries, occupies a pivotal position in the national economy.It has a rotation of 90 degrees, the plug body is a sphere, with a circular through hole or channel through its axis.Ball valve in the pipeline is mainly used to cut off, distribution and change the direction of the flow of the medium, it only needs to rotate 90 degrees of operation and a small rotational torque can be closed tightly.Ball valve is most suitable for switch, cut-off valve use, V-type ball valve.In addition to the pipe parameters, the electric valve should pay special attention to the environmental conditions of its use. Because the electric device in the electric valve is an electromechanical equipment, its use state is greatly affected by its use environment.Normally, electric ball valve, butterfly valve in the following environment should pay special attention to use.
