It uses fluorine-lined material to protect valve body and valve seat, improves the corrosion resistance of valve. The working principle of double-jaw fluorine-lined butterfly valve is relatively simple. It controls the flow of medium by rotating valve disc. When the valve is in the open state, a channel is formed between the valve disc and the valve seat, and the medium can flow smoothly through the valve. When the valve is in the closed state, a seal is formed between the valve disc and the valve seat, preventing the flow of medium. The rotation angle of the valve disc is usually between 0° and 90°, and when it is rotated to 90°, the valve is fully open.
