There are some differences in structure and application between stainless steel flanged ball valves and ball valves. The following is a specific comparison of the two

I. Structural Differences

Connection method

Stainless steel flanged ball valve: It is connected through flanges. Flange connection is a common connection method, suitable for occasions that require frequent disassembly.

Ball valves: There are various connection methods, including flange connection, welding connection, threaded connection and clamp connection, etc. The appropriate connection method can be selected according to specific requirements and usage environment.

Material and Structure

Stainless steel flanged ball valve: The main material is stainless steel, which has excellent corrosion resistance and high-temperature resistance. Its structure is compact and it is easy to operate and maintain.

Ball valves: They are made of various materials, including cast steel, stainless steel, alloy steel, etc., and can be selected based on the characteristics of the medium and the working environment. The structure is also relatively simple, but it may vary due to factors such as connection methods and sealing forms.

Ii. Application Differences

Usage scenarios

Stainless steel flanged ball valves: Widely used in fields such as petroleum, chemical engineering, power, environmental protection, water conservancy, heating, water supply and drainage, industry, and machinery. It has low fluid resistance and reliable sealing performance, and is suitable for various fluid media and temperature ranges.

Ball valves: They are also widely used in multiple fields, but the specific application scenarios may vary due to factors such as connection methods, pressure levels, and sealing forms. For example, pneumatic ball valves and electric ball valves are suitable for occasions that require remote control. Three-way ball valves are suitable for occasions where media are distributed and the flow direction of the medium is changed.

Functional characteristics

Stainless steel flanged ball valve: Its main features are low fluid resistance, simple structure, convenient operation, easy maintenance and wide application range. Its sealing surface material widely uses plastic, which has good sealing performance and has also been widely used in vacuum systems.

Ball valve: In addition to having some characteristics of stainless steel flanged ball valves, it may also have other functional features due to factors such as connection methods and sealing forms. For example, welded ball valves are suitable for occasions where the pipeline system structure is required to be compact and have good sealing performance. Soft-sealed ball valves have excellent sealing performance and can achieve zero leakage. They are generally used in pipelines with corrosive media at normal temperature and pressure.

Iii. Summary

There are differences in structure and application between stainless steel flanged ball valves and ball valves. The specific type of valve to be chosen depends on the actual requirements and working environment. When selecting the type, factors such as the characteristics of the medium, working pressure, temperature range and connection method need to be taken into consideration to ensure the normal operation and service life of the valve.
