Soft Seal PTFE Fluorine Lined Flange Electric Actuator Butterfly Valve

The anti-corrosion fluorine lined butterfly valve adopts a two-piece valve body combination. When the valve seat and the valve body lining are integrated, only the all plastic valve seat and the plastic butterfly plate and the media joint product can withstand any medium corrosion except for the “molten alkali metal and element fluorine”. The inner surface of the valve body channel is smooth. The flow resistance is small, CV value is high, the flow capacity is strong, the support moment is moderate, and the elastic cushion seat with four-stage sI rubber is completely medium
