Fluorine-lined Valve Factory Explains The Selection And Application Of Fluorine-lined Plastic Valves

In modern industry, Lined Valve is widely used in various harsh chemical processes due to its excellent corrosion resistance. However, in order to ensure the long-term stable operation of the valve, the fluorine-lined valve factory reminds everyone that you must pay attention to the following key points during the selection and application process.
1. Consideration of medium temperature
When selecting a fluorine-lined plastic valve, the first thing to consider is the temperature of the medium. Different fluorine-lined materials have their specific temperature resistance range. Beyond this range, the material may degrade, affecting the sealing performance and life of the valve. Therefore, understanding and confirming the medium temperature is crucial for selecting a suitable valve.
2. Avoid negative pressure environment
Fluorine-lined plastic valves are generally not designed for negative pressure environments. Under negative pressure, the fluorine lining layer in the valve may fall off, causing damage to the valve. Therefore, when designing the system, ensure that no negative pressure is generated at the location of the valve.
3. Control of pressure and differential pressure
In the selection and application of valves, it is necessary to ensure that the working pressure and differential pressure are within the allowable range of the valve. Excessive pressure will not only damage the valve, but may also cause leakage or even rupture of the valve.
4. Screening of media conditions
Special attention should be paid when fluoroplastic-lined valves are used in media containing hard particles, crystals or impurities. These substances may scratch the fluoroplastic lining layer and affect the sealing performance of the valve. In this case, Hastelloy can be considered as the valve core and valve seat material to improve the wear resistance of the valve.
5. Selection of diameter size
Correctly selecting the diameter size of the valve is crucial to ensure the normal operation of the system. Too large or too small valve diameters will affect the flow rate, which in turn affects the efficiency of the entire system. Therefore, selecting the appropriate valve diameter according to flow requirements is a key step to improve system performance.
In summary, the reasonable selection and application of fluoroplastic-lined valves can not only improve the reliability of the system, but also extend the service life of the valve. In practical applications, we should fully understand the technical conditions, reasonably select valves, and ensure that they operate in good condition.
