API ball valve

Ruitong Valve suppling many kind of ball valves :Floating type ball valve,Trunnion ball valve API flanged ball valve;API carbon steel ball valve; API stainless steel ball valve,Threaded ball valve etc. API ball valve is a valve with its ball floating (not fixed by a trunnion) inside the valve body, it drifts toward to the downstream side and tightly pushes against the seat under the medium pressure to ensure sealing reliability. The 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.
