Something about floating ball valve

A 2pc floating ball valve is also know as two piece floating ball valve, which not only is assembled by two parts, consisting of a valve body and a bonnet, but also is a valve with its ball floating inside the valve body, which differs from a trunnion ball valve. Consequently, this kind of valve takes advantage of both the two kind valves.

Totally speaking，the 2PC floating ball valve has simple structure, good sealing performance but the seat material is required to withstand the workload since the sealing pressure is bared by the seat ring. Due to unavailability of high performance seat material, floating ball valve is mainly used in middle or low pressure application.
