A Ball valve is a quarter-turn rotary motion valve that uses a ball-shaped disk to stop or start the flow.
It resembles a plug valve in many ways. When a port in the ball is in line, it allows flow whereas when you
rotate the valve 90 degrees, solid part of the ball stop the flow.
Most ball valves are of the quick-acting type, which requires a 90° turn of the valve handle to operate the valve.
But in case large size valve which required considerable force to open or close the valve, the gear-operated
actuator is used. With this arrangement, a small handwheel is enough to operate a fairly large valve.
In this article, I have covered following types of Ball Valves that used in piping.
Side entry or split body
Applications of the Valve
It can be used in different types of fluid services as an on-off stop valve that provides bubble-tight shutoff.
It can be used in air, gaseous, and vapor services as well as hydrocarbon services.
Metal seated valves can be used in high-pressure & temperature applications.
it is widely used with instrument tubing to connect instruments.
It is quick to open and close type that provides bubble-tight reliable sealing in high-pressure temperature applications.
It is smaller and lighter than a gate valve of the same size and rating.
Several designs of ball valves offer the flexibility of selection so that you can choose the valve that suits your requirements.
Easy to operate and Cost-effective maintenance.

The three-piece ball valve with the internal thread and the gate valve are the same type of valve.
The difference is that the closing part is a ball, and the ball rotates around the center line of the valve body to
achieve a valve that is opened and closed.
The three-piece ball valve only needs to be rotated tightly with a 90-degree rotation and a small rotational torque.
The completely equal valve body cavity provides a small, straight flow path for the medium. It is generally considered
that the ball valve is most suitable for opening and closing directly, and the ball valve has been designed to have a throttling
and control flow. The main characteristics of the ball valve are it's compact structure, easy operation and maintenance,
suitable for general working media such as water, solvent, acid and natural gas, and also suitable for working media with
poor working conditions such as oxygen, hydrogen peroxide, methane and ethylene. The ball valve body can be integral or modular.
