The electric PFA lined butterfly valves work best in chemical, biological and pharmaceutical processes. The high-temperature PFA lining provides better chemical resistance and corrosion protection than standard metal valves. Electric PFA lined butterfly valves operate with self-lubrication which provides better operation than manual operated valves and decreases the need for regular maintenance. The 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.
FEATURES
Easily automate with the ISO5211 direct mounting pad, designed for convenient integration.
Three PTFE impregnated SS316L bearings to ensure precise alignment of the disc-shaft, guaranteeing optimal performance.
PTFE-liner that protects against chemically toxic and highly corrosive media. Additionally, our rubber liner is versatile and suitable for a wide range of industrial applications.
The stable sealing between the liner and disc is achieved through the use of a silicon rubber energized back behind the PTFE seat. This innovative design offers a wide range of temperature capabilities, ensuring optimal performance.
By utilizing a one-piece disc-shaft design, valve torque is minimized and Kv is enhanced, resulting in improved performance.
Achieve a bubble-tight seal even at full pressure rating.
This item can be easily disassembled, allowing for material-specific recycling possibilities.
