    Description

     Ceramic Double Disc Gate Valve

    Design Features:



    • The Ceramic Double Disc Valve is ceramics-to-ceramics sealing, also named as parallel double disc valve, or ceramic double disc valve or ceramic double gate valve.
    • The standard end connection of ceramic double disc valves is flanged type, but if the installation space is limited, wafer type is available.
    • Three piece bodies of Ceramic Double Disc Valves are very easy for assemble and reliable for maintenance.
    • Self-cleaning disc design allows disc to move freely and avoid being scratched by solid particles.

    Temperature range

    • Usually working temperature of pneumatic conveying system is not so high, but under some conditions like economizer valves in coal fired power plant, the working temperature may be up to 450 ℃. Then special design of ceramics and packing material will be considered.
    • Detailed information about working temperature of our Ceramic Double Disc Valves, please contact us at sales@foyovalve.com.
    • Normal working temperature of Ceramic Double Disc Valves: -29 °C ~ +200 °C
    • High temperature design of Ceramic Double Disc Valves: -29 °C ~ +450 °C
