What is the difference between fixed and floating ball valves?

In the field of valves, fixed ball valves and floating ball valves are two common types. They have significant differences in structure, working principle and application. I will talk to you about the differences between these two types of ball valves, and analyze their performance, advantages and disadvantages, to provide you with practical reference information. By understanding these differences, I will be better able to select the appropriate ball valve type to meet specific application needs.

1. Fixed ball valve: stability and support

The design feature of a fixed ball valve is that the ball is fixed and will not move with changes in fluid pressure. This design allows fixed ball valves to perform well in high-pressure and high-temperature environments because the tight fit between the ball and seat reduces leakage and wear. In addition, fixed ball valves usually have better fluid control characteristics and are suitable for situations where precise flow control is required. However, fixed ball valves are relatively expensive to manufacture and repair, and may suffer from high operating torque in some cases, bronze plug valve.

2. Floating ball valve: flexible and adaptive

Unlike fixed ball valves, the ball of a floating ball valve can move freely under the action of fluid pressure. This design allows the floating ball valve to have better adaptive capabilities in response to pressure changes and temperature changes. Floating ball valves are relatively cheap to manufacture and repair and have low operating torque, making them favored in many applications. However, due to the larger gap between the ball and the seat, floating ball valves may not seal as well as fixed ball valves and may perform worse in high-pressure and high-temperature environments.

3. Performance comparison: each has its own strengths

In terms of performance, fixed ball valves and floating ball valves each have their own advantages. The fixed ball valve has good sealing performance and is suitable for high pressure, high temperature and highly corrosive fluid control situations. The tight fit between its ball and valve seat can reduce leakage and wear, ensuring safe and stable operation of the system. In addition, the fixed ball valve has excellent fluid control characteristics and can meet the demand for precise flow adjustment. However, fixed ball valves have high manufacturing and maintenance costs and large operating torque, which limits their application scope to a certain extent, bronze wafer check valve.

Floating ball valves have good adaptive capabilities in response to pressure changes and temperature changes, so their application range is relatively wide. Floating ball valves are less expensive to manufacture and repair and have lower operating torque, making them an economical and practical choice in many applications. In addition, the structure of the floating ball valve is relatively simple and easy to maintain and replace. However, due to its relatively poor sealing performance, more frequent maintenance and replacement may be required in high pressure, high temperature and corrosive environments.

4. Application Suggestions: Choose according to needs

When selecting a fixed ball valve or a floating ball valve, factors such as application requirements, system conditions and economics should be fully considered. For high pressure, high temperature and highly corrosive fluid control occasions, fixed ball valves may be a better choice to ensure the safe and stable operation of the system. In some low-pressure, normal temperature or weakly corrosive applications, floating ball valves can be considered to reduce costs and operational difficulty. In addition, factors such as the material, size and connection method of the valve need to be considered during the selection process to ensure its matching and compatibility with the system, high temperature check valve.

5. The following is the summary I made

Through an in-depth discussion and analysis of fixed ball valves and floating ball valves, I can better understand the differences and characteristics of these two valve types. With the continuous advancement and innovation of science and technology, more new valve technologies and materials may appear in the future, providing more possibilities for my choice. I need to maintain attention and research on new technologies and new materials in order to keep abreast of and master the latest industry dynamics and development trends to provide strong support for the optimization and upgrading of fluid control systems.
