Wafer PTFE Fully Lined Multi-Standard Butterfly Valve

1. The wafer-style valve body is engineered to fit between flanges of various standards. ?The body of Multi-Standard Butterfly Valve has a universal face-to-face dimension (e.g., per API 609 or EN 558) and bolt hole alignment to accommodate these standards without modification.

• • • PN10/PN16 (European standard, EN 1092-1): Common in water and wastewater systems, rated for 10 or 16 bar.
    • ANSI/ASME B16.5 Class 150: North American standard, widely used in chemical and industrial applications.
    • DIN 2501: German standard, often overlapping with PN10/PN16.
    • BS 4504: British standard, compatible with PN10/PN16.
    • JIS B2220 (5K/10K): Japanese standard, used in Asian markets.

2. Corrosion resistance: PTFE fully lined butterfly valve has excellent corrosion resistance to various corrosive liquids, including strong acids, strong alkalis, etc.

3. Temperature Range: PTFE fully lined Multi-Standard Butterfly Valve can withstand higher temperatures than EPDM，while It has a temperature range of approximately -250°C to +260°C (-418°F to +500°F).

4. Versatility: PTFE is also called “Plastic King” in China, so it is suitable for different types of media, whether it is corrosive or non-corrosive fluid.

5. Low Friction: PTFE has a low coefficient of friction, reducing wear on valve components, as a result, it can increases service life and reduces maintenance.
