Lined ptfe butterfly valve

The PTFE Lined Butterfly Valve is an innovative solution designed for a variety of applications, particularly those involving corrosive and aggressive media. It features a wafer style split body design, which provides superior durability and reliability. The lining of the valve is made from Polytetrafluoroethylene (PTFE), a material renowned for its exceptional chemical resistance and low friction properties. This ensures that even highly aggressive and corrosive media can be safely controlled without damaging the valve.

The pfa Lined Butterfly Valve offers manual operation, but it also comes with the option for pneumatic actuation, providing flexibility based on your operational needs. Its state-of-the-art design provides excellent shutoff protection, ensuring bubble-tight sealing for optimal performance. Furthermore, the valve’s high Cv value indicates its efficiency in allowing fluid flow.

Additionally, the butterfly valve is available in various patterns, including wafer, lugged & tapped, or double flanged, making it suitable for a wide range of installations. The body of the valve is typically made of epoxy-coated ductile iron, which is non-wetted, further enhancing its resistance to corrosive substances.

In terms of sizes, the PTFE Lined Butterfly Valves come in a broad spectrum, with the PFA lined valves available up to 12 inches and PTFE lined valves available from 14 to 24 inches. This range of sizes ensures that whatever your flow control needs, there is a PTFE Lined Butterfly Valve to suit your requirements.

In conclusion, the PTFE Lined Butterfly Valve is a high-performance, versatile, and durable solution for flow control in various industries. Its superior chemical resistance, range of sizes, and design options make it an excellent choice for applications dealing with aggressive and corrosive media.

PTFE is the preferred material for corrosive applications in chemical industry.
PU is the preferred material for abrasive applications.
EPDM is the preferred rubber for water industries.
NBR is the preferred rubber for oil transportation.
FPM is the preferred rubber for wide range of medium composition and temperature.
Wafer design makes the valve convenient for connection between flanges and save length in pipe line.
