Floating ball valve is a special type of valve, and the following is a detailed introduction to it:
1, Working principle
The ball of the floating ball valve has no supporting shaft and relies only on two valve seats for support. At the same time, the valve stem is connected to the ball in a movable manner, making the ball in a "floating" state. Under the pressure of the medium, the sphere can produce a certain displacement and be tightly pressed against the sealing surface at the outlet end, thereby ensuring the sealing performance of the outlet end.
Structural Features
Simple structure: The floating ball valve has a relatively simple structure and is easy to manufacture and maintain.
Good sealing performance: The sealing surface material between the ball and the valve seat is excellent, such as hard alloy or polytetrafluoroethylene, which is wear-resistant, corrosion-resistant, and has good sealing performance.
Low fluid resistance: The ball can be turned on and off by rotating 90 degrees in the pipeline, resulting in low resistance when the fluid passes through.
Quick opening and closing: Due to the floating characteristics of the sphere on the valve seat, the opening and closing action is more rapid and flexible.
Multiple additional structures: Floating ball valves are usually equipped with locking devices, stem anti flying structures, anti-static devices, fire-resistant structures, etc., to improve their safety and reliability.
3, Scope of application
Floating ball valves are widely used in general working media such as water, solvents, acids, natural gas, as well as media with harsh working conditions such as oxygen, hydrogen peroxide, methane, and ethylene. In addition, it is also suitable for industries such as chemical, petroleum, natural gas, metallurgy, as well as long-distance natural gas pipelines containing hydrogen sulfide media, high impurities, and severe corrosion.
4, Advantages
Simple structure, easy to manufacture and maintain.
Good sealing performance and low fluid resistance.
Quick opening and closing, easy to operate.

So,Floating ball valves are suitable for a wide range of media, including water, oil, and gas. They can even handle difficult tasks such as oxygen and hydrogen peroxide, but it is important to pay attention to temperature and pressure and not exceed their capabilities
