Points To Note When Using Ptfe Lined Valves

With the rapid development of modern industry, Lined Valve and its various pipeline accessories have been rapidly applied and promoted in various fields such as petroleum, printing and dyeing, and chemical industry, showing strong vitality. As a project in the project, it has attracted great attention and favor from various engineering design units and construction units. It is a promising product with market potential.
The price of PTFE-lined valves is relatively high, and the working environment is harsh. It is either toxic and harmful chemical substances or highly corrosive acids, alkalis or organic solvents. Improper use will cause significant economic losses and serious consequences. Correct use and maintenance of valves can extend the service life of fluorine-lined valves, prevent all kinds of accidents, and ensure the normal operation of pipelines. Therefore, the following points must be noted during use:
1. Before use, read the product manual carefully.
2. Use within the pressure, temperature, and medium range specified on the nameplate or manual.
3. When using, prevent the fluorine-lined valve from generating excessive pipeline stress due to temperature changes, minimize temperature changes, and add U-shaped expansion joints before and after the valve.
4. It is forbidden to use a lever to open and close the fluorine-lined valve. Pay attention to the opening and closing indication position and limit device of the fluorine-lined valve. After opening and closing, do not force it to close to avoid premature damage to the fluoroplastic sealing surface.
5. For the violent and long-term vibration of the pipeline, measures should be taken to eliminate it to avoid damage to the PTFE-lined valve.
