casting ball valve Description
Cast iron ball valves employ precision manufacturing processes, ensuring tight sealing between the valve seat and disc through fine machining. This capability effectively prevents fluid leakage. Additionally, cast iron ball valves can enhance sealing performance further by incorporating sealing fillers, ensuring stable operation of fluid systems.

Advantages of cast iron ball valves include:
1. Low Fluid Resistance: Full-bore ball valves have minimal flow resistance.
2. Simple Structure, Compact Size, Lightweight.
3. Secure and Reliable: They feature two sealing surfaces, often made of various plastics for excellent sealing performance, achieving complete sealing. They are widely used in vacuum systems.
4. Convenient Operation: Quick opening and closing with a 90° rotation, facilitating remote control.
5. Easy Maintenance: Simple structure with typically movable sealing rings, making disassembly and replacement convenient.
6. Isolation of Sealing Surfaces: When fully open or closed, the ball and valve seat's sealing surfaces isolate from the medium, preventing erosion during fluid passage.
7. Wide Application Range: Available in diameters ranging from millimeters to meters, suitable for applications from high vacuum to high pressure.
8. Suitable for Media with Suspended Solids: Due to their wiping action during operation, they can be used with media containing suspended solid particles.
