How To Ensure The Normal Operation Of Ptfe Lined Valves In Industry?

Points to note when operating Lined Valve in industry:
1. Before use, carefully read the instructions for use of the product.
2. Use within the range of pressure, temperature and medium according to the parameters on the nameplate or clear regulations.
3. When using, prevent the change of pipeline stress caused by temperature changes in the PTFE-lined valve, minimize temperature changes, and increase the expansion of the valve before and after the valve.
4. In some unstable and easily decomposed media, the valve will be damaged or leaked, and measures should be taken to eliminate or.
5. For toxic, flammable, explosive and corrosive media, it is forbidden to replace the valve under pressure.
6. If the pipeline oscillates for a long time, measures should be taken to eliminate it and prevent damage to the PTFE-lined valve.
7. During the application of the PTFE-lined valve, the sealing surface of the fluoroplastic lining is soft, and the sealing surface is often damaged by crystalline media, solid particles, etc., causing sealing leakage. It is necessary to promptly discover, repair or replace the seal.
8. Some valves are used to adjust the flow during use. High-speed media will cause premature damage to the sealing surface. In this case, the seal should be replaced in time.
