Product details
Overview of Pneumatic Fluorine lined Stop Valve:
The pneumatic fluorine lined globe valve (J641F46) has the characteristics of compact structure, high strength, and strong corrosion resistance. It is specially designed to control various anti-corrosion valves containing corrosive media. The valve cavity is entirely lined with anti-corrosion fluorine material, suitable for pipelines with various concentrations of corrosive gases, liquids, and solution media at temperatures ranging from -10 ℃ to 150 ℃. The valve seat of the pneumatic fluorine lined globe valve adopts integral polymer as the sealing material, which has excellent sealing performance in a wide temperature and pressure range; The opening and closing element (valve disc) is a valve driven by the valve stem and moves up and down along the central axis of the valve seat. It is mainly used to connect or cut off the medium in the pipeline, but cannot be used for throttling.
Characteristics of Pneumatic Fluorine lined Stop Valve:
1. Pneumatic fluorine lined globe valve has a simple structure, easy installation and maintenance, small working stroke, and adopts a top-down flow structure.
2J641F46 Pneumatic Stop ValveAdopting lining technology, the lining material is generally made of fluoroplastics such as FEP (F46) and PCTFE (F3), 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 lined fluorine globe valve has good sealing performance, and the adhesive of the sealing material can make the lining adhesive have strong affinity with the pipe wall, with goodDurableIt has advantages such as anti scaling performance and long service life.

Instructions for using pneumatic fluorine lined globe valve:
1. The sealing pair of the fluorine lined flange globe valve stored for a long time should be in a slightly separated state to avoid permanent deformation of the sealing surface due to long-term compression, which may affect the sealing performance and service life.
2. When manually operating the pneumatic fluorine lined globe valve, it is not allowed to use other levers to forcefully open or close the valve.
3. When installing fluorine lined globe valves with directional requirements, attention should be paid to the flow direction of the medium as indicated by the arrow on the valve body, and ensure easy operation and maintenance.
4. The repaired pneumatic fluorine lined globe valve must be tested and qualified according to relevant standards before installation.
