ANSI PTFE Lined Wafer Type Butterfly Valve – ED71PTFE

Products Description

  • The Lined Wafer Type Butterfly Valve bi-directional flow is possible at maximum operating pressure. Since the valve port corresponds to the piping diameter, a high flow capacity is guaranteed.
    It features ease of maintenance, repeatable on-off, long life durability.
    The concentric design is commonly used in the power generation, brewing, water and food industries and suitable for both gaseous and liquid service. Typically applied in chemical/petrochemical process, food and beverage, and pulp and paper etc.
    Lining material: PTFE, PFA, FEP, GXPO etc.
    Connection type: wafer, flange, lug etc.
    Operation methods: manual, worm gear, electric, pneumatic and hydraulic actuator.
    Elite lined three-way ball valves are available as per the needs of applications in additional sizes and other than standard materials.
