The ball valves are normally used as positive shut off valves. The positive shut off is attained because of the soft seats. Special design is also available with ball having shaped port for  regulation. Metal seated ball valves are also available for high temperature service.

According to structural features, ball valve is classified into: floating ball valve, trunnion mounted ball valve, multi way ball valve.

According connection, ball valve is classified into: flanged ball valve, fully welded ball valve and socket welded ball valve, ring type jointed (RTJ) ball valve.

According to materials used for body, ball valve is classified into casting ball valve, forged ball valve, stainless steel ball valve, etc.
