    Features/Applications

    Features

    • Quick startup

      The original MIYAWAKI thermoelement swiftly discharges initial cold condensate and air.

    • No steam leaks

      Operates below saturation temperature, resulting in no steam leaks and great energy saving performance.

    • Resilient against dirt and scale

      Dirt and scale are effectively discharged thanks to a generously designed valve hole and large flow surface area in the valve.

    • Anti-freeze functionality

      The valve remains fully open once the operation stops and drains completely.

    • Easy maintenance

      By removal of the cover all internal parts of the trap can be exchanged, leaving the trap installed in line.

    Typical applications

    For radiators
    Suitable for heating systems in places such as hotels, schools, hospitals, and offices.
    The W3 can also be used in intermediate and pipe end sections of low-pressure heating lines.
