Description & Features：
Fluorine Lined Diaphragm Valve is a special form of shut-off valve. Its working principle is mainly driven by compressed air to drive the drive screw to make the valve core move up and down, while pulling the diaphragm up and down to close and open. Besides, its switches are oriented and move smoothly. The use medium of Fluorine lined diaphragm valve is any organic solvent or reagent, dilute or concentrated inorganic acid, alkali, ketone, aromatic hydrocarbon, chlorinated hydrocarbon and so on.
● Fluorine Lined Diaphragm Valve has the characteristics of compact structure, simple, small volume and beautiful appearance.
● Its diaphragm compression can be adjusted automatically, the pressure is even, and the seal is reliable.
● It mainly has three modes of operation: manual, electric, pneumatic.
● The diaphragm is installed in the spool with a push-in type, which is easy to replace.
