Principle of operation The shaft/plug arrangement is eccentric (Figs.3 and 4). The double-eccentric design of the rotary plug valve is achieved in combination with the offset of the plug's pivot. The double-eccentric design allows the plug to lift off the seat immediately. Standard direction of flow = FTO (medium opens) (Fig.5). On request FTC (medium closes) possible. Opening direction= Plug closes clockwise Opening angle= 90° Fig.3 Plug movement with double-eccentric arrangement The flow coefficient depends on the opening angle of the valve. Using positioners, the natural characteristic...
