According to the classification of shell / main body materials, ball valves can be divided into:
1. Metal valves: such as carbon steel valves, alloy steel valves, stainless steel valves, cast iron valves, titanium alloy valves, Monel valves, copper alloy valves, aluminum alloy valves, lead alloy valves, etc.
2. Metal body lined valves: such as rubber lined valves, fluorine lined valves, lead lined valves, plastic lined valves and enamel lined valves.
3. Non metallic valves: such as ceramic valves, glass valves and plastic valves.
There are many domestic manufacturers of ball valves, and most of the connection sizes are not unified. It is mainly divided into the following categories:
