    Steam Traps E Series | Inverted Bucket Steam Traps ESU5

    Features/Applications

    Features

    • No condensate logging on primary side

      Intermittent or continuous discharge depending on condensate loads means no condensate stacking up on the primary side.

    • Superb durability

      Offers superb durability thanks to the SCCV System valve and robust super lever, as well as stainless steel internal components.

    • Easy maintenance

      For quick and easy maintenance, this model can be repaired directly in line.

    • Condensate recovery

      With its high degree of back pressure tolerance, this model supports condensate recovery at pressures up to 90% of the upstream pressure.

    • Complete steam containment

      A double steam separation mechanism (implemented with a U-shaped duct and inverted bucket) provides reliable steam separation and ensures trap tightness.

    • Free from steam and air locking

      This model is free from steam and air locking due to a small air vent hole in the top of the bucket (discharges hot air and non-condensable gases).

    *’SCCV System’ is an abbreviation of Self Closing and Centering Valve System.

    Typical applications

    Body and cover made of stainless steel, and suitable for food equipment, medical equipment and other applications.

    ●To keep the drawing simple, bypass lines, valves, and other required equipment are not displayed. 
    ●If you wish to recover condensate, attach a check valve (CV model) and shut off valve on the trap’s outlet side
