Sanitary Valve is to place polytetrafluoroethylene resin (or processed profile) on the inner wall of the steel or iron valve pressure-bearing part by molding (or inlaying). So do you know what are the precautions when selecting and using fluorine-lined valves?

The precautions when selecting and using fluorine-lined valves are as follows:

Medium characteristics: Understand the chemical properties and temperature of the processed medium to ensure that the selected fluorine-lined valve can withstand these conditions.

Valve material: In addition to the lining material, other parts of the valve (such as the valve body and valve stem) also need to use appropriate materials to ensure overall corrosion resistance and strength.

Pressure level: Select the appropriate valve pressure level according to the working pressure of the system.

Size and connection method: Select the corresponding fluorine-lined valve according to the size and connection method of the pipeline.

Operation method: Select different operation methods such as manual, electric, and pneumatic according to actual needs.

Maintenance and replacement: Although fluorine-lined valves are corrosion-resistant, they also need regular inspection and maintenance, and worn parts should be replaced when necessary.
Fluorine-lined valves use lining technology for all places in the valve body that can be reached by the medium. The lining material is generally made of fluoroplastics such as FEP (F46) and PCTFE (F3). It can be used in pipelines with various concentrations of sulfuric acid, hydrochloric acid, hydrofluoric acid, aqua regia and various organic acids, strong acids, strong oxidants and other corrosive media.
