First, the basic characteristics of high-performance floating ball valve
High-performance floating ball valve is a kind of valve that uses the ball to rotate 90 degrees to achieve opening and closing. Its main features are simple structure, compact size, light weight, easy maintenance, and has a good cut-off performance. Due to its internal floating design, the ball can be automatically centred under the pressure of the medium, thus improving the sealing performance and service life. In addition, this type of ball valve usually uses PTFE, PFA and other polymer materials as a seal, these materials not only have excellent chemical stability and high temperature resistance, but also can effectively prevent media leakage, to ensure the safe operation of the system.

Second, the application of high-performance floating ball valves in the chemical industry
1. strong corrosive media control chemical production process often encounter a variety of strong acids, strong alkalis and other corrosive chemicals. Traditional metal valves in these extreme conditions are easily damaged by corrosion, resulting in leakage or failure. High-performance floating ball valves made of corrosion-resistant materials, such as stainless steel, Hastelloy, etc., can maintain stable performance in harsh chemical environments, extending the service life of the valve.
2. high temperature and high pressure occasions, some chemical reactions need to be carried out in high temperature and high pressure conditions, which puts forward higher requirements for the valve. High-performance floating ball valves can withstand temperatures up to 600 ℃ and tens of MPa pressure, while maintaining good sealing effect, ensuring the safety and continuity of the production process.
3. precision flow control in fine chemical production, the ratio of raw materials and flow control requirements are very strict. High-performance floating ball valves can achieve fine control of flow through precise opening adjustment to meet the needs of different processes.
4. environmental emission control with the increasingly stringent environmental regulations, chemical companies need to waste gas, waste water treatment before discharge. High-performance floating ball valves can be used to regulate fluid flow in treatment facilities to help meet environmental standards.
