What is a ball valve used for?
Ball valve is the most used fluid shutoff valve in upstream oil and gas production facilities, both onshore and offshore. They are also used in fuel gas systems feeding furnaces. Plug valves present the following advantages: Resistance to high pressure.
What are the advantages of a ball valve?
Ball Valve plays a vital role in daily life as they are used day to day basis, say it from bicycles or automobiles, jet airplanes or any industry. There are different sizes and shapes of valves and each has various dimensions, functions and applications to it.
The industry has numerous use of the Ball valves and in order to ensure that these valves remains functional during the operation, it is safe to maintain it before it gets corroded away. Regular cleaning and lubrication to ensure the smooth functionality is key to their life span.
These valves are categorized into five general bodies which includes three piece bodies, two piece bodies ,single body top entry, a split body and welded. The following qualities make them an excellent choice for controlling various applications and sometimes they are preferred over any other valves which has less control in the throttling applications.
Advantages Of Ball Valves
They provide leak-proof service
Open and close quickly
Compared to gate valves, they have very small dimensions
Compared to gate valves, they are lighter
The multi designed flexibility does not exist in the Gate or Globe valve, and hence it lowers the amount of valves needed
These valves are manufactured in different sizes and shapes providing flexibility in selection
The high quality valves provide safe service under high temperature and high pressure conditions, and
Compared to other valves, they are controlled with less force.
The main disadvantages of these valves are as follows:
The position of the valve handle is rotated,
Could not be used for throttling, and
These valves with drive mechanism should be installed upright.
What are the disadvantages of ball valves?
They’re therefore not recommended for sustained throttling applications. Wear and tear: When used to regulate the wrong types of fluids, such as slurries, ball valves can stick in position and become jammed due to suspended particles being trapped. This can cause the valve to wear, or to become damaged or stuck.
What are the types of ball valves?
There are five general body styles of ball valves: single body, three-piece body, split body, top entry, and welded. The difference is based on how the pieces of the valve—especially the casing that contains the ball itself—are manufactured and assembled.
Why is it called a ball valve?
A ball valve is a shutoff valve that controls the flow of a liquid or gas by means of a rotary ball having a bore.
