Introduction To Fluorine Lined Check Valve

Lined Check Valve, also known as fluoroplastic check valve, is an automatic anti-corrosion valve that automatically opens and closes the valve disc by the flow of the medium itself, used to prevent the reverse flow of the medium. Its internal components, such as the valve disc and the valve seat, are lined with fluoroplastics (such as PTFE or FEP) to enhance the corrosion resistance of the valve.
The main features of the fluorine-lined check valve are:
1. Good corrosion resistance, suitable for various corrosive or highly corrosive media, such as acids, alkalis, salts, oxidants, etc.
2. Wide operating temperature range, can be used for medium pipelines at different temperatures.
3. Compact structure, small size, light weight, easy installation.
4. Fluoroplastic seal is used, reliable sealing, low leakage rate.
5. Simple structure, easy disassembly and convenient maintenance.

Precautions for installation and use of fluorine-lined check valve:
1. The fluorine-lined check valve should be installed on a horizontal pipeline, and the medium flow direction should be consistent with the direction of the arrow on the valve body.
2. The valve should be checked regularly during use to ensure its normal operation.
Application of fluorine-lined check valve:
Fluorine-lined check valve is widely used in chemical, petroleum, pharmaceutical, food, metallurgy, electric power and other industries, and is suitable for pipeline systems that transport various corrosive media.
