Fluorine Lined Control Valve

Fluorine Lined Control Valve is a kind of anti–corrosion straight through single seat control valve. The inner wall of the valve body and the components inside the valve are lined with F46 anti–corrosion materials. The PTFE inside the valve will be completely separated from the outside media.

It is used for corrosion of all chemical media, and has excellent sealing. It is equipped with multi–spring pneumatic diaphragm actuator or electric actuator. It has features: small volume, light weight, large output force, easy to install.
