What Are The Advantages Of Cast Iron Ball Valves?

Cast iron ball valves are used on pipelines with non-corrosive media such as water and steam with a working temperature of ≤150°C for opening and closing; its biggest advantage is quick opening and closing. In addition, what are its advantages? Today I will introduce the advantages of cast iron ball valves, as follows:

What are the advantages of cast iron ball valves

1. The fluid resistance is small, and the full-bore ball valve has no flow resistance at all.

2. Simple structure, small size, and lightweight.

3. Tight and reliable. It has two sealing surfaces, and now the sealing surface materials of ball valves are widely used in various plastics, with good sealing performance and complete sealing. It has also been widely used in vacuum systems.

4. It is easy to operate and quick to open and close. It only needs to rotate 90° from fully open to fully closed, which is convenient for long-distance control.

5. It is easy to repair, the structure of the ball valve is simple, the sealing ring is generally movable, and it is more convenient to disassemble and replace.

6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium. When the medium passes through, it will not cause corrosion on the sealing surface of the ball valve.

7. It has a wide range of applications, with a diameter ranging from a few millimeters to a few meters, and can be used from high vacuum to high pressure.

8. Because the ball valve has scrubbing properties during the opening and closing process, it can be used in the medium with suspended solid particles.
