Ball valves include: floating ball valve, fixed ball valve, track ball valve, V-shaped ball valve, three-way ball valve, stainless steel ball valve, cast steel ball valve, forged steel ball valve, ash unloading ball valve, sulfur resistant ball valve, pneumatic ball valve, electric ball valve, ferrule ball valve and welded ball valve.
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:
The ball of the ball valve is floating. Under the action of medium pressure, the ball can produce a certain displacement and press tightly on the sealing surface of the outlet end to ensure the sealing of the outlet end.
