What is the maximum temperature that a PTFE-lined butterfly valve can withstand?
On this page
The lining material of a PTFE-lined butterfly valve is a fluoropolymer, with polytetrafluoroethylene (PTFE) being the most commonly used type. PTFE offers excellent chemical resistance, allowing the valve to handle highly corrosive media such as strong acids and alkalis. In addition, PTFE exhibits a broad temperature tolerance, with an operating range from -196 °C to 200 °C.
The temperature range of PTFE does not directly indicate the maximum operating temperature of a PTFE-lined butterfly valve. As a consumable component, the valve is subject to continuous corrosion and erosion from the process media during operation. The temperature limits of PTFE are determined under ideal laboratory conditions; in practice, factors such as manufacturing process, production environment, and technical quality can reduce the actual temperature tolerance of the valve, making it lower than the theoretical values.
Based on statistical observations and analysis, the maximum operating temperature of a PTFE-lined butterfly valve varies by manufacturer. Valves produced by manufacturers using high-quality materials can withstand up to 200 °C, while typical commercially available valves generally tolerate around 150 °C.
PTFE-lined butterfly valves utilize the excellent properties of polytetrafluoroethylene to effectively isolate the process media from the valve body, providing corrosion resistance. These valves are widely applied in industries such as oil and gas, chemical, and environmental protection.
Under ambient temperature and pressure, PTFE-lined butterfly valves offer a cost-effective solution and can serve as alternatives to stainless steel butterfly valves. Given that these valves are often used in corrosive service conditions, it is essential to ensure their quality and safety during procurement.
