  •  Pneumatic fluorine lined globe valve

Product overview

The pneumatic fluorine lined stop valve (j641f46) has the characteristics of compact structure, high strength and strong corrosion resistance. It is specially used to control various kinds of anticorrosive valves containing corrosive media. The valve cavity is fully lined with anti-corrosion fluorine materials, which is suitable for pipelines with various concentrations of corrosive gas, liquid and solution medium at - 10 ℃ ~ 150 ℃. The valve seat of pneumatic fluorine lined globe valve adopts integral polymer as sealing material, which has excellent sealing performance in a wide range of temperature and pressure; the valve with opening and closing parts (disc) driven by the valve stem and moving 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 it can not be used for throttling.
 Structure of pneumatic fluorine lined globe valve
Features of pneumatic fluorine lined globe valve:
 
1. The pneumatic fluorine lined stop valve has the advantages of simple structure, convenient installation and maintenance, small working stroke and top-down flow direction.
2. J641f46 pneumatic stop valve adopts lining process. The lining materials are generally FEP (F46) and PCTFE (F3) and other fluoroplastics, which can be applied to various concentrations of sulfuric acid, hydrochloric acid, hydrofluoric acid, aqua regia, various organic acids, strong acids, strong oxidants and other corrosive media.
3. It has the advantages of anti fouling, anti fouling and good sealing performance.

Operating instructions for pneumatic fluorine lined globe valve:
1. The sealing pair of the fluorine lined flange globe valve stored for a long time should be in the state of micro opening and separation, so as to avoid the 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 force the valve to open or close with the help of other levers.
3. When installing the fluorine lined stop valve with directional requirements, the flow direction of the medium should be in the direction indicated by the arrow on the valve body, and ensure the convenience of operation and maintenance.
4. After maintenance, the pneumatic fluorine lined stop valve should be tested and qualified according to relevant standards before use.
