What is A Ball Valve?

• Ball Valves 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.

Advantages of Ball Valves

- Ball valves are contain a compact and low-maintenance design that requires no lubrication

- Ball valves are cost-effective among all of the valves

- Ball valves are 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.

- Ball valves are provide leak-proof service.

-  Ball valves are opening and closing quickly.

- Ball valves have multi-way design flexibility.

Disadvantages of Ball Valves

- 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.

Key Features of Ball Valves

Application of Ball Valves

- 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.
