Brief explanation of RTFE seat butterfly valve
A RTFE (reinforced tetrafluoroethylene) seat butterfly valve is a type of valve commonly used in industrial applications to regulate the flow of fluids through pipes. It consists of a metal disc, or “butterfly,” mounted on a rod within a circular housing. When the valve is closed, the butterfly blocks the flow of fluid. When the valve is open, the butterfly rotates perpendicular to the flow of fluid, allowing it to pass through the valve. RTFE is often used as a valve seat material due to its excellent chemical resistance and temperature stability, making it suitable for use in harsh environments such as the chemical industry. The use of RTFE in valve seats helps to prolong valve life, reduce maintenance requirements, and protect downstream equipment from damage caused by fluid contamination or leakage.
