    Description

    Electric pfa lined butterfly valve

    Electric PFA lined butterfly valves are ideal for applications involving chemical, biological and pharmaceutical processes. The high-temperature PFA lining offers superior chemical resistance and corrosion protection over standard metal valves. Additionally, electric PFA lined butterfly valves are self-lubricating, providing a smoother operation than manual operated valves and reducing the need for regular maintenance. These electric butterfly valve can be used in a wide range of industrial process control applications such as shutoff, throttling or regulating service in chemical plants, oil refineries, water treatment units and food processing facilities. Furthermore, they require less energy consumption while offering efficient control over flow rate and pressure. Invest in an electric Teflon lined butterfly valve today for superior results!

    FEATURES

    • ISO5211 direct mounting pad for easy automation
    • Isolation height according to plant prescription
    • Dirtscraper prevents moisture penetrating into the shaft area
    • Three PTFE impregnated SS316L bearings are provided for precision alignment of the disc-shaft
    • 3 layers sealing system ensures environment protection
    • PTFE seat and rubber seat version interchangeable each other• PTFE-liner for chemically toxic and highly corrosive media, rubber liner for various of industry applications
    • Silicon rubber energized back behind PTFE seat makes the sealing between liner and disc stable and offer a wide range of temperature
    • One-piece disc-shaft design reduces the valve torque and increases Kv
    • PTFE or rubber lined disc design option avoids high cost by expensive metal in corrosive applications
    • Bubble-tight shut of at full pressure rating
    • Can be disassembled, material-specific recycling possible
    • Wave shape flange face design ensures the flange sealing of seat face not damaged by flange pressing, also avoids shrink of seat inside diameter because of flange pressing
