Product Detail

Q41F46 Flour lined ball valve

Fluorine-lined ball valves are opened and closed by a ball with a circular through hole that rotates with the stem around the center line of the body.Special molding process is adopted to make the sealing surface compact and good, and v-type PTFE packing combination makes the valve reach zero leakage;The ball and stem are cast as a whole, which eliminates the possibility of the stem rushing out of the pressure parts due to pressure changes, and fundamentally ensures the safety in use.All plastic lining technology is adopted to withstand the strong corrosion of medium.
