The fully lined fluorine butterfly valve is a kind of valve whose opening and closing parts are disc type, which can open, close and adjust the fluid channel by reciprocating about 90 degrees. This valve has the following outstanding advantages:

1. Simple structure, small size and light weight, small installation size, small driving torque, easy and rapid operation.

2. It can have good flow regulation function and closing sealing characteristics at the same time.

3. It has good corrosion resistance, especially suitable for occasions with severely corrosive media, such as sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, strong alkali, aqua regia, etc.

4. The valve body of the fully lined fluorine butterfly valve adopts a split design. The sealing at both ends of the valve shaft is controlled by adding fluorine rubber to the rotating base surface between the butterfly plate and the valve seat to ensure that the valve shaft does not come into contact with the fluid medium in the cavity. Replace the valve Very convenient when the shaft is installed, the valve can be completed without disassembling the pipe.

5. The fluid resistance is small. The effective flow area of medium and large diameter pneumatic butterfly valves is large when fully open, and the opening and closing is quick and labor-saving.
