Fully lined fluorine butterfly valve is a type of valve that uses a disc type opening and closing element to rotate back and forth about 90 degrees to open, close, and regulate fluid channels. The structure is simple, the volume is small, the weight is light, the material consumption is low, the installation size is small, the driving torque is small, the operation is simple and fast, and it also has good flow control function and closing sealing characteristics,

Fully lined fluorine butterfly valve: 1. The center line butterfly valve is a butterfly plate and valve seat that are concentric within a 360 ° circumference (center line), with bidirectional sealing function, and pressure and flow can be freely adjusted; 2. Adopting adjustable elastic pin positioning. Accurate positioning and simple structure.

3. Four level loading elastic seal ensures absolute zero leakage inside and outside the valve; a、 The special transition curve at the connection between the shaft head and the butterfly plate circumference and the reasonable interference fit of the valve seat; b、 The end face of the shaft head adopts a combination of elastic O-ring, rigid washer at the shaft shoulder, and elastic rubber pad; c、 The radial direction of the shaft adopts a combination of O-ring and metal pad; d、 The valve seat is embedded in the groove of the valve body with elastic strips.
