Wafer-type fluorine-lined butterfly valve body channel has a smooth inner surface, low fluid resistance, high CV value, strong flow capacity, and moderate torque. It adopts a four-level sealing structure and is equipped with an elastic lining of temperature-resistant and anti-aging SI rubber outside the sealing surface. The valve seat is cushioned to completely achieve zero leakage of the medium.
