Product Overview

Half lined fluorine butterfly valve uses a butterfly plate that rotates together with the valve stem as an opening and closing element to achieve valve opening, closing, and adjustment. Lined fluorine butterfly valve is made of polymer material with thick lining technology on the overcurrent components, valve body, butterfly plate, and valve stem, which has excellent corrosion resistance and is suitable for any concentration of acid, alkali, salt, oxidant, reducing agent, organic solvent and other media.

Structural Features

Half lined fluorine butterfly valve is a valve seat that is fully sealed with PTFE. Compared with fully lined ones, it has outstanding sealing performance but a shorter service lifeStructural characteristics of semi lined fluorine butterfly valve: 1. Small in size, light in weight, easy to operate, and convenient for installation and maintenance. 2. Excellent and reliable sealing performance, zero leakage, and long service life.

3. The flow characteristics tend towards a straight line and rotate 90 degrees to open and close. 4. Simple structure, quick switch, 90 degree rotation for opening and closing. 5. Can replace various valves such as gate valves, globe valves, plug valves, hose valves, and diaphragm valves. 6. Pneumatic and electric devices can be configured according to user needs to meet the needs of remote control and program control. 7. Replace the lining material of the parts to be suitable for various media.
