2 Piece Floating 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.
Series - 150 To 300
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. DAGO floating ball valve series featuring 2PC split body side entry or uni body, a very popular design in floating ball valve.
Design Features
- The sealing material of ball valve is widely used in plastic with good sealing which has widely used in vacuum system
- The fluid confficient of vave is equal to the same length of the pipe
- Easy to operate,On-off rapidly,only 90°needed from open to close,suitable for remove control
- Wide range of application,DN from several millimeters to several meters,pressure from high vacuum to high pressure can be applied
