    Features/Applications

    Features

    • Suitable for medium capacity steam processes

      Capable of moving continually to change the degree of valve opening according to the incoming condensate to provide maximum heat exchange capacity.

    • High discharge capacity

      A double-port balanced valve is adopted to discharge larger capacity with a smaller body.

    • Easy maintenance

      Internal screen can be taken out quickly and easily without removal of trap from pipe line.

    • Condensate recovery

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

    • Quick startup

      Internal thermostatic air vent automatically discharges of air/gases and cold condensate during startup.

     

    Typical applications
