Stainless steel 304/316L lined PTFE flange ball valve is a type of ball valve used for handling highly corrosive media. Its internal lining is made of stainless steel 304 or 316L, and the external coating is made of PTFE or similar materials to provide good sealing and corrosion resistance. Here are some characteristics and uses of this ball valve:

1. Stainless steel 304/316L lining: Stainless steel 304 and stainless steel 316L are commonly used stainless steel materials for lining. They have good corrosion resistance, especially stainless steel 316L, which is suitable for handling various corrosive media. These stainless steel liners are used to provide structural strength, while PTFE is coated internally to enhance sealing. 2. PTFE flange: This type of ball valve usually comes with a flange connection, which can be connected to the flange connection port of the pipeline system through bolts and nuts. PTFE flange is a commonly used flange connection method in the chemical industry because PTFE is an excellent non stick and corrosion-resistant material, suitable for many corrosive media. 3. Application: Stainless steel 304/316L PTFE lined flange ball valve is widely used for handling highly corrosive media such as acids, alkalis, oxidants, solvents, etc. They are widely used in industrial fields such as chemical, petroleum, pharmaceutical, food and beverage, and wastewater treatment. The design of these ball valves makes them suitable for environments that require high corrosion resistance and reliable sealing performance. 4. Temperature and pressure range: The performance and applicability of stainless steel 304/316L PTFE lined flange ball valves may vary depending on the manufacturer and model. Therefore, before selecting and installing, it is important to carefully understand your specific needs and system requirements and choose the appropriate ball valve based on these requirements. In summary, this type of ball valve is designed to provide reliable fluid control in industrial applications with high corrosion requirements, using stainless steel 304/316L liner and PTFE flange to ensure performance and durability.
