How To Use And Maintain Ptfe Lined Valves Correctly

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 received great attention and favor from various engineering design units and construction units. It is a promising product with market potential.
The PTFE-lined valve has the dual functions of switching and flow regulation. It can conveniently open and close the gas line without affecting the flow, ensuring the repeatability of the flow. In addition, the opening speed of the PTFE-lined valve is slow, which reduces the impact of the instantaneous pipeline pressure on the instrument, which is equivalent to adding a damper, thereby greatly extending the service life of the PTFE-lined valve. The PTFE-lined valve is specially used to control corrosive or highly corrosive media. The inner surface of the valve body is covered with various fluoroplastics that can be selected. It is suitable for different working temperatures and fluid pipelines, and has the characteristics of high strength and good corrosion resistance.
The price of fluorine-lined valves is relatively high, and the working environment is harsh. It is either toxic and harmful chemicals, or highly corrosive acids, alkalis or organic solvents. Improper use will result in 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. So how to correctly use and maintain PTFE-lined valves? For staff who are new to PTFE-lined valves, please read the product instructions carefully before use. In addition, it is necessary to strictly follow the pressure, temperature and medium range specified on the valve nameplate or in the instructions, and must not exceed it. For fluorine-lined valves on pipelines with toxic, flammable, explosive, and highly corrosive media, it is strictly forbidden to replace the packing under pressure. Even if the PTFE-lined valve has an upper sealing function in design, it is not recommended to replace the packing of the valve under pressure. In addition, it is strictly forbidden to use a lever to open or close the PTFE-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.
Only by correctly using and maintaining the PTFE-lined valve can the service life of the fluorine-lined valve be extended and the normal operation of the pipeline be guaranteed.
