The floating ball valve has a simple structure and good sealing performance, but the ball bears all the load of the working medium and is transmitted to the outlet sealing ring. Therefore, it is necessary to consider whether the sealing ring material can withstand the working load of the ball medium. When subjected to high pressure impact, the ball may deviate. This structure is generally used for medium and low pressure ball valves. The main characteristics of a ball valve are its compact structure, reliable sealing, simple structure, and easy maintenance. The sealing surface and spherical surface are often in a closed state, which is not easily eroded by the medium and is easy to operate and maintain. It is suitable for general working media such as water, solvents, acids, and natural gas, and is also suitable for media with harsh working conditions. The contact parts between the ball valve and the medium are made of corrosion-resistant stainless steel. This soft sealed ball valve is used for general working media such as water, solvents, acids, and natural gas, and is also suitable for harsh working conditions such as corrosive media such as oxygen, hydrogen peroxide, nitric acid, acetic acid, caustic soda, etc. Soft sealed stainless steel flange ball valves are commonly used in medical and health equipment, food machinery, chemical acid and alkali corrosive equipment, and pipeline systems.
