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.
Floating
Trunnion Mounted
3 Way
Top entry
Side entry or split body
Three-piece 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 applied in food , bewerage, wine, pharmaceutical and chemical industries.
Advantages
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 valve body can be replaced in any connections and the length will not change.
