    Automatic double back-flush filterHYDRAULIcs & Mining Technology

    The automatic double back-flush filter provides filtration of hydraulic fluids.

    This double filter consists of two filter chambers, each containing one filter insert.

    The two chambers are linked to each other within a filter block by two-way valve cartridges in such a way that fluid can flow through the two chambers in parallel.

    Switching one of the directional valve cartridges causes the relevant filter chamber to be blocked or opened.

    Hydraulic actuation of the directional valve cartridges is effected either by a double solenoid valve mounted on the double filter or by a pilot valve operated by hand.
