Cast Steel Ball Valve

    Cast steel ball valve is a commonly used type of valve, whose main component is a circular sphere with a hole in the middle. The medium flow in the pipeline can be opened or closed by rotating the sphere. The cast steel structure ball valve has a compact structure, easy operation, good sealing performance, and is suitable for various working media, including water, solvents, acids, and natural gas. In addition, cast steel ball valves can also adapt to harsh working conditions such as oxygen, hydrogen peroxide, methane, and ethylene

Working principle
     The working principle of cast steel ball valve is based on the rotational motion of the sphere. When the sphere rotates 90 degrees, the hole between the sphere and the valve seat can be fully opened or closed, thereby achieving rapid switching of the medium. Due to the isolation of the sealing surface between the sphere and the valve seat in the closed state, the medium will not cause erosion of the valve sealing surface when fully open or fully closed

Advantages and disadvantages of cast steel ball valves
     The advantages of cast steel ball valves are their simple structure, easy operation, reliable sealing, and easy maintenance. However, it also has some potential drawbacks, such as seal failure that may occur under certain extreme conditions. Therefore, when selecting and using cast steel ball valves, it is necessary to fully consider their applicability and limitations.

      The main advantages of cast steel ball valves are their excellent corrosion resistance and high pressure bearing capacity, making them suitable for pipeline systems with various liquids, gases, and non corrosive media. Stainless steel ball valves perform better in terms of corrosion resistance, especially suitable for more demanding corrosive environments. Electric and pneumatic ball valves provide the convenience of remote control and are suitable for situations that require automated control. Other valve such as globe valve, gate valve, and butterfly valve more commonly used in certain specific application scenarios. For example, globe valves are suitable for situations that require fine flow control, gate valves are suitable for situations that require frequent opening and closing, and butterfly valves are suitable for situations where space is limited or fast response is required.
