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

1、 Structural differences

Connection method

Stainless steel flange ball valve: Connected through flanges, flange connection is a common connection method, suitable for occasions that require frequent disassembly.

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

Material and Structure

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

Ball valve: Various materials, including cast steel, stainless steel, alloy steel, etc., can be selected according to the characteristics of the medium and the working environment. The structure is relatively simple, but may vary due to factors such as connection methods and sealing forms.

2、 Application differences

Usage scenario

Stainless steel flange ball valve: widely used in petroleum, chemical, power, environmental protection, water conservancy, heating, water supply and drainage, industry, machinery and other fields. It has low fluid resistance, reliable sealing performance, and is suitable for various fluid media and temperature ranges.

Ball valve: It is also widely used in multiple fields, but the specific usage scenarios may vary due to factors such as connection method, pressure rating, and sealing form. For example, pneumatic ball valves and electric ball valves are suitable for situations that require remote control; Three way ball valves are suitable for distributing media and changing the flow direction of media.

Functional Features

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

Ball valve: In addition to some characteristics of stainless steel flange ball valves, it may also have other functional features due to connection methods, sealing forms, and other factors. For example, welded ball valves are suitable for applications that require a compact pipeline system structure and good sealing performance; Soft sealed ball valves have good sealing performance and can achieve zero leakage. They are generally used in normal temperature and pressure pipelines with corrosive media.

3、 Summary

Stainless steel flange ball valves and ball valves have differences in structure and application, and the specific type of valve chosen depends on actual needs and working environment. When selecting, factors such as the characteristics of the medium, working pressure, temperature range, and connection method need to be considered to ensure the normal operation and service life of the valve.
