Problems to be noted in the use of fluorine-lined valves

Due to the continuous improvement of new materials and lining technology, fluorine-lined valves are favored by valve manufacturers and users because of their safety, reliability and high cost performance. Valves are becoming more and more extensive.

fluorine valve in use should pay attention to the following problems:

1. before use, carefully read the product instructions.

2. Use within the range of pressure, temperature and medium specified on the nameplate or instructions.

3. It is forbidden to use the lever to open and close the valve. Pay attention to observe the indicating position and limiting device of the fluorine-lined valve. After the opening and closing are in place, do not force the valve to close, so as to avoid premature damage to the rubber sealing surface.

4. Prevent excessive pipeline stress caused by temperature change of fluorine-lined valve during use, minimize temperature change, and increase U-shaped expansion joints before and after the valve.

5. For some media are unstable and easy to decompose (such as the decomposition of some media will cause volume expansion and abnormal increase of working pressure), which will cause valve damage or leakage, measures should be taken to eliminate or limit the factors causing unstable media decomposition. In the valve selection, should consider the medium is not stable and easy decomposition may cause changes in working conditions and choose to have automatic pressure relief device fluorine valve.
