    Steam Traps G Series | Ball Float Steam Traps G20N

    Features/Applications

    Features

    • Suitable for steam process lines

      The floating mechanism discharges condensate immediately at saturation temperature, preventing condensate stacking up on the primary side. Ideally installed in applications where condensate logging cannot be accepted.

    • Time shortening to start up

      Automatically discharges initial air and cold condensate. The diaphragm air vent follows the saturation temperature and prevents air and steam locking.

    • Energy saving design

      Achieves high sealing performance even in situations with extremely small amounts of condensate and reduces steam loss thanks to a precision polished float and three point support mechanism.

    • Condensate recovery

      With its high degree of back pressure tolerance, this model supports condensate recovery.

    Typical applications

    Suitable for use in F&B process equipment, cleaning devices, air conditioning and similar applications.
