How to correctly use and maintain PTFE lined valves

With the rapid development of modern industry, PTFE lined valve The rapid application and promotion of various pipeline accessories in various fields such as petroleum, printing and dyeing, and chemical industry have shown strong vitality. As a project in engineering, it has received great attention and favor from various engineering design and construction units, and is a sunrise product with market potential.
PTFE lined valves have dual functions of switching and flow regulation, which can easily open and close the gas path without affecting the flow rate, ensuring the repeatability of the flow. In addition, the slow opening speed of PTFE lined valves reduces the impact force of instantaneous pipeline pressure on instruments, which is equivalent to adding a damper, greatly extending the service life of PTFE lined valves. PTFE lined valves are specifically designed to control corrosive or highly corrosive media. The surface of the valve body cavity is covered with various fluoroplastics for selection, suitable for different working temperatures and fluid pipelines. They have the characteristics of high strength and good corrosion resistance.
Fluorine lined valves are expensive and operate in harsh working environments. They are either toxic or harmful chemicals, or highly corrosive to various acids, bases, or organic solvents. Improper use can result in significant economic losses and serious consequences. Proper use and maintenance of valves can extend the service life of fluorine lined valves, prevent various accidents, and ensure the normal operation of pipelines. So how to correctly use and maintain PTFE lined valves? For personnel who are new to PTFE lined valves, please carefully read the product manual before use. In addition, it is necessary to strictly follow the pressure, temperature, and medium range specified on the valve nameplate or instruction manual, and not exceed them. For fluorine lined valves on pipelines with toxic, flammable, explosive, and highly corrosive media, it is strictly prohibited to replace the packing under pressure. Even though PTFE lined valves have sealing functions in their design, it is not recommended to replace the valve packing under pressure. In addition, it is strictly prohibited to use levers to open or close PTFE lined valves. Pay attention to the indication position and limit device of the fluorine lined valve. After the opening and closing are in place, do not forcefully close it to avoid premature damage to the fluoroplastic sealing surface.
Only when used and maintained correctly PTFE lined valve To extend the service life of fluorine lined valves and ensure the normal operation of pipelines.
