一、 Main overview of g41f46 fluorine lined diaphragm valve:

G41f46 fluorine lined diaphragm valve is a special type of valve with cut-off function. Its closing part is composed of a diaphragm made of steel valve disc and soft materials (rubber and fluoroplastic composite), and separates the inner cavity of the valve body from the inner cavity of the bonnet, so as to achieve the purpose of cutting off the medium in the pipe.

二、 Features of g41f46 fluorine lined diaphragm valve:

1. The composite diaphragm valve separates the inner cavity at the lower part of the valve body from the inner cavity of the bonnet and forms a DC channel with it, so that the valve stem, disc and other internals at the upper part of the diaphragm are completely isolated from the medium, eliminating the packing sealing structure, and the internal and external leakage of the medium can be avoided at the same time;

2. The valve with Teflon fluoroplastic lining layer, which uses the diaphragm composed of FEP (Teflon) fluoroplastic and full rubber, can be suitable for all kinds of highly corrosive media except "molten alkali metal and elemental fluorine".

3. As an actuator, the diaphragm is prone to fatigue fracture due to frequent opening and closing. It should be replaced regularly according to the working conditions and the characteristics of the medium.

4. Corrosion resistance and recommended temperature of fluoroplastics "performance table of fluoroplastics lining for valves and pipeline accessories".
