Product Description

Product description
1.summarize
Fluorine-lined diaphragm valve is a special type of valve with cutoff function. Its opening and closing parts are composed of steel disc and diaphragm made of soft material (rubber and fluoroplastic compound), and the inner cavity of valve body is separated from the inner cavity of valve cover to cut off the medium in pipe.

2.Characteristics
1. The compound diaphragm separates the inner cavity of the lower part of the valve body from the inner cavity of the valve cover, and forms a direct current channel with it, so that the internal parts such as the valve stem and the disc on the upper part of the diaphragm are completely isolated from the medium, thus omitting the packing sealing structure, and avoiding the internal leakage and external leakage of the medium at the same time.
2. Diaphragm composed of FEP(Teflon) fluoroplastics and synthetic rubber and valve with Feflon fluoroplastics lining layer can be suitable for all kinds of strong corrosive media except "molten alkali metal and elemental fluorine".
3. The diaphragm as an actuator is prone to fatigue fracture due to frequent opening and closing, and should be replaced regularly according to working conditions and medium characteristics
