What Factors Affect The Performance Of A Threaded Ball Valve?

Threaded Ball Valve withstand not only the internal pressure of the fluid but also the stress of the pipeline, the weight of the ball, and other additional forces. Their design must consider factors such as sealing and strength, corrosion, and manufacturing processes.

Existing ball valve body formulas are a modification of pressure vessel formulas, and in most cases, ball valves are considered pressure vessels. However, the shape of a ball valve body is much more complex than that of a pressure vessel. Even with the same valve body, not only do different types of ball valve bodies have different shapes, but the dimensions of each component in a fluorine-lined valve are also completely different. Traditional methods make it difficult to calculate different parts of different shapes and sizes separately, so they are often assumed to have the same thickness.

Fluorine-lined valves are used to control corrosive or highly corrosive media. The valve's internal cavity is coated with various fluoroplastics, making it suitable for a wide range of operating temperatures and fluid pipelines. It offers high strength and corrosion resistance. Fluorine-lined valves perform two functions: a switch and a flow regulator. Opening and closing the gas line can be easy without affecting flow, ensuring flow repeatability. Due to their slow opening speed, transient pressure in the pipeline has a minimal impact on the equipment. The damper significantly extends the service life of the fluorine-lined valve.
