Product features

The pneumatic fluorine lined stop valve (J641F46) has the characteristics of compact structure, high strength, strong corrosion resistance, etc. It is specially used to control various anti-corrosion valves containing corrosive media. The valve chamber is entirely lined with anti-corrosion fluorine materials, and is suitable for pipelines with various concentrations of corrosive gases, liquids and solution media with temperatures ranging from - 10 ℃ to 150 ℃. The valve seat of the pneumatic fluorine lined globe valve uses integral polymer as the sealing material, which has excellent sealing performance in a wide range of temperature and pressure; The valve whose opening and closing parts (valve disc) are driven by the valve stem and move up and down along the central axis of the valve seat is mainly used to connect or cut off the medium in the pipeline, but cannot be used for throttling.
Structure of pneumatic fluorine lined stop valve
Features of pneumatic fluorine lined stop valve:
 
1. The pneumatic fluorine lined stop valve is simple in structure, convenient in installation and maintenance, small in working stroke, and adopts a top-down flow structure.
2. J641F46 pneumatic stop valve adopts lining process, and the lining material is generally FEP (F46), PCTFE (F3) and other fluoroplastics, which can be applied to pipelines with various concentrations of sulfuric acid, hydrochloric acid, hydrofluoric acid, aqua regia, various organic acids, strong acids, strong oxidants and other corrosive media.
3. The flange fluorine lined stop valve has good sealing performance. The adhesive of sealing material can make the lining adhesive have a strong affinity with the pipe wall. It has good anti rust and anti scaling performance and long service life.

Instructions for use of pneumatic fluorine lined stop valve:
1. The sealing pair of fluorine lined flange stop valve stored for a long time shall be slightly opened and separated to avoid permanent deformation of the sealing surface under long-term pressure, which will affect the sealing performance and service life.
2. When manually operating the pneumatic fluorine lined stop valve, it is not allowed to forcibly open or close the valve with the help of other levers.
3. When installing fluorine lined stop valves with directional requirements, pay attention to the flow direction of the medium along the arrow on the valve body, and ensure easy operation and maintenance.
4. The repaired pneumatic fluorine lined stop valve can be installed only after passing the test according to relevant standards before use.
