  2. A full working cycle is obtained by turning the knob with 20 slots by 180?.

    There are two types of crane boxes installed in mixers:

    Worm
    1. In this case, used for sealing rubber cuffs.
    2. The principle of operation is the following - a rubber gasket should be pressed against the seat of the crane and block the way to the water.
    3. Adjustment of the water supply is 2-3 revolutions of the crank handle or flywheel.

    The “weakest link” in this design is a rubber cuff that quickly fails.

    With ceramic inserts
    1. In this case, the main elements that carry out the opening and closing of the flow of water are ceramic plates with symmetrical holes of the same shape.
    2. The first ceramic plate is fixed in the body of the product, the second is mounted on the flywheel stem.
    3. The work of the crane is to rotate and offset or align the holes in the plates. As a result, water is supplied or blocked in the mixer.

    3. The locking washer is necessary for fixing the crane box with the stem in the mixer housing.
    4. The adapter allows you to make a rigid connection of the rotary rod with the upper ceramic plate. Its shape depends on the crane box model.
    5. The free rotation of the stem is due to the ceramic plates above and below.
    6. A rubber sealing cuff is needed to ensure that the axle box adjoins the valve seat.

    Tip: before starting the assembly and installation of the crane box, perform a routine inspection of the mixer seat, determining its current state.

    The instruction allows the use of a ceramic element only with a water filter. It must be installed either in front of the mixer, or at the entrance to the dwelling. Otherwise, sand and dirt from the water supply network will quickly disable the ceramic inserts.
