    AD402 Working Principle:

    1) When no pressure is applied inside the bowl:

    Float descends of its own weight and valve closes the chamber hole. Piston is pushed down by spring , and drain passes through the chamber's long hole to enter the housing and is discharged.


    2) When pressure is applied inside the bowl:
    When pressure is 0.1MPa or more, it overcomes the forces of spring, allowing the piston to ascend, and comes in contact with O-ring. Thus, the inside of the bowl is isolated from the outside.

    3)When drain has accumulated:
    Float ascends due to flotation and opens the chamber hole, allowing the pressure to enter the chamber. Piston descends due to internal pressure and the force of spring, and the accumulated drain is discharged through drain guide.
