As the name suggests, ball valves are valves that use a ball to control the flow of substances from one opening to the next. These valves work by allowing the hole to be open, blocked, or open partially to regulate the flow of gas/liquid. Ball valves are the ideal choice for using with gases as they are able to offer better sealing. They are very versatile as they support pressures up to 700 bars and temperatures up to 200°C and sizes typically range from 0.5 cm to 30 cm. They are easy to operate and repair as they contain a simple structure. They are designed with special measures that permit only a 90-degree rotation which is required for the opening and closing of ball valves. These valves are a notable industrial choice because of their reliable and air-tight sealing when in the closed position.
- They contain a compact and low-maintenance design that requires no lubrication
- They are cost-effective among all of the valves
- The biggest advantage of ball valves is that they have poor throttling characteristics that can cause the seat of a ball valve to easily erode.
- They provide leak-proof service.
- They open and close quickly.
- Ball valves have multi-way design flexibility.
- Ball valves are not suitable for permanent throttling.
- In residual fluids, the particles in the fluid collide with the surfaces and stick to them. This may cause leakage, abrasion, and other problems.
- Ball Valves are used for flow and pressure control and shut off for corrosive fluids, slurries, normal liquid and gases.
- They are used in the oil and natural gas industry, but also find a place in many manufacturing sectors, chemical storage, and even residential uses
