Product Description

Pneumatic fluorine lined stop valve (J641F46) has the characteristics of compact structure, high strength, strong corrosion resistance, is dedicated to control a variety of corrosive media containing anticorrosive valve, valve cavity all use anticorrosive fluorine material integral lining, suitable for the temperature of -10ºC ~ 150ºC of various concentrations of corrosive gas, liquid and solution media on the pipeline. Pneumatic fluorine-lined globe valve seat with integral polymer as sealing material, has excellent sealing performance in a wide range of temperature and pressure; Opening and closing parts (disc) driven by the valve stem and along the central axis of the valve seat for lifting movement, in the pipeline is mainly used to connect or truncate the medium in the pipeline, but can not be throttling.




Pneumatic lined fluorine globe valve features
1. The pneumatic fluorine lined stop valve has the advantages of simple structure, convenient installation and maintenance, small working stroke and top-down flow structure.
2, J641F46 pneumatic stop valve using lining process, lining material generally used FEP (F46) and PCTFE (F3) fluorine plastics, can be applied to various concentrations of sulfuric acid, hydrochloric acid, hydrof-luoric acid, aqua Wang and various organic acids, strong acids, strong oxidants and other corrosive media pipeline.
3, the flange lining fluorine cut-off valve sealing good, sealing material of the adhesive can make the lining glue and pipe wall has a strong affinity, has good resistance and anti-scaling performance, long service life and other advantages.

Instructions for use of pneumatic fluorine lined globe valve
1. The sealing pair of the long-term storage fluorine-lined flange globe valve should be micro-open and separated, to avoid permanent deformation of the sealing surface under long-term pressure, affecting the sealing performance and service life.
2. When manually operating the pneumatic fluorine-lined globe valve, it is not allowed to forcibly open or close the valve with the help of other levers.
3, there are directional requirements of the fluorine lined cut-off valve in the installation should pay attention to the flow of the medium should be along the direction of the arrow on the valve body, and ensure that the operation and maintenance is convenient.
4, after the maintenance of the pneumatic fluorine lined stop valve before use according to the relevant standards to test qualified before installation.
