    Product Description

    A PTFE lined butterfly valve is a type of butterfly valve that uses a disc made of PTFE (polytetrafluoroethylene) to control the flow of fluid. PTFE is a type of plastic that is known for its chemical resistance, high temperature tolerance, and low friction properties. The PTFE lining is applied to the disc, which is attached to a stem that runs through the valve body. As the stem is rotated, the disc moves into and out of the flow path, allowing or blocking the flow of fluid.

    The main advantage of a PTFE lined butterfly valve is that it offers excellent chemical resistance against a wide range of acids, alkalis, and other chemicals. This makes it suitable for use in applications where the fluid being transported is highly corrosive or toxic.

    PTFE lined butterfly valves are available in a wide range of sizes and pressure ratings, and can be made from materials such as carbon steel, stainless steel, and alloy steels. They are also available in different designs, such as wafer, lug and double flange, and also with different types of actuators and accessories to meet specific requirements.

    PTFE lined butterfly valves are known for its tight shut off and are available in both manual and actuated (pneumatic or electric) operation. They are also suitable for use in a wide range of temperatures, making them suitable for use in a variety of industries such as chemical, petrochemical, pharmaceutical, and power generation. They are also suitable for use in high-purity applications, as PTFE is highly resistant to contamination and does not release any toxic substances into the fluid.
