BW Ends Floating Ball Valve
Butt Welded Cast Steel Ball Valve
A floating ball valve with floating ball(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.
For floating ball valves, there are kinds of end connection acc. to the pipeline requirements, flanged, SW, BW, etc. BW end requirements is very high precise machining technician at welding clearance, blunt edge size and BW angle, machine equipment is very important as well.
