The manual PTFE-lined flanged ball valve is a type of valve commonly used in industrial applications where corrosion resistance and chemical compatibility are crucial. It is designed to regulate the flow of corrosive fluids by utilizing a PTFE (polytetrafluoroethylene) lining on the valve body and ball.The PTFE lining helps protect the valve from corrosive fluids, ensuring long-term durability and reliability.The valve is equipped with flanged ends, allowing it to be securely connected to the pipeline using bolts or screws. The flanged connection provides a tight and leak-free seal.The manual PTFE-lined flanged ball valve is commonly used in industries such as chemical processing, pharmaceuticals, water treatment, and oil and gas, where corrosive fluids need to be controlled with precision.
