PTFE valve seats are components used in valves to provide a tight and reliable sealing surface between the valve disc or ball and the valve body. PTFE valve seats find applications in various industries, including chemical processing, pharmaceutical, oil and gas, food and beverage, and many others. They are commonly used in different types of valves, including ball valves, butterfly valves, plug valves, and diaphragm valves.
PTFE valve seats offer exceptional resistance to a wide range of chemicals, acids, solvents, and corrosive substances. They can withstand exposure to aggressive media without degradation, making them suitable for use in chemically harsh environments.
PTFE valve seats can handle high temperatures, ranging from cryogenic conditions up to approximately 260°C (500°F). They retain their sealing properties even at elevated temperatures, making them ideal for applications involving heat or thermal cycling.
PTFE has a low coefficient of friction and excellent deformability, allowing it to conform to the shape of the valve disc or ball and create a reliable seal. PTFE valve seats provide excellent sealing properties, preventing leakage and ensuring efficient operation of the valve.
PTFE has a low coefficient of friction, resulting in reduced wear, minimizing the risk of galling or sticking. This property allows for smooth movement of the valve disc or ball, reducing operating torque and extending the lifespan of the valve.
PTFE has a non-stick surface, preventing the adhesion of substances and making the valve seat easy to clean and maintain. This property is advantageous in applications where cleanliness and prevention of contamination are critical.
PTFE valve seats can be custom-machined to match specific valve designs and dimensions. They are designed to withstand the operating conditions of the valve, including pressure, temperature, and the nature of the fluid being handled.
