Ball valves is known as a quarter turn valve that is used in a hollow. It is mainly used in a field where the closing and opening of more than two to three valves are done where a quick action is needed.
Structure of a valve
A ball consists of a valve body which is present in a large spherical shape with a central hole. The centre hole is of the equal diameter of the pipe that is mounted deep inside the valve. The ball provides the conduit to the valve which is being rotated to restrict the flow of liquid. Valve helps in providing very little amount of resistance.
The gate valve of the ball can be best used in fully closed or fully open positions. Yu can freely go with the one quarter turn and keep it in the fully closed positions. While installing the valve properly, you may require a proper closing and opening of the valve, where the isolation of the pipe can be held properly.
Types of ball valve
- Single body valve
- Three-piece body valve
- Split body valve
- Top entry valve
- Welded valve
The major difference among all these valves is because of the position in which they are placed and the pieces according to which they are categorised. And the other factors are the manner in which they are assembled and manufactured.
Effective use of valve
Valve are more effective when they are tightly used and are more reliable to use and control the flow. Ball valves are more effective than the gate valves as they provide a good aspect of longevity, but a bit costlier because of its high-level functioning. They are best proven for control and shutoff applications. It is very easy to open and close the ball valves, and the chances of leakage is quite low.
In a very few cases, ball valve failed to get sealed and fluid is easily passed. But it happened very rarely. Most of the times the functionality of sealing is done in a proper way and avoid all the leakage options.
The easy to install the valve is using various orientations and the deviation must be held using a vertical technique of pipe set up. To avoid valve failure, make sure that the clearance of the set valve is properly done according to the valve guide professionals.
