A filter assembly for filtering a liquid, comprising:
a filter housing including a top plate, a bottom plate, a cylindrical wall extending from the top plate to the bottom plate, and an outlet passage;an inlet distributor including a lowermost plate, a cylindrical wall extending downwardly between the bottom plate and the lowermost plate and defining an interior volume, and an inlet passage;a plurality of cylindrical filter elements extending vertically from the bottom plate and through the filter housing toward the top plate, each of the cylindrical filter elements including an inlet orifice and an interior that is in fluid communication with the interior volume of the inlet distributor via the inlet orifice;a plurality of movable cleaning devices, each movable cleaning device being positioned relative to a respective one of the cylindrical filter elements and including a stroke device, a stroke bar, and a filter cleaning element arranged on the stroke bar; and a plurality of valves, each valve including a valve body sized and shaped to sealingly engage the inlet orifice of a respective one of the cylindrical filter elements, a thrust rod reciprocatingly extending through the lowermost plate, and a drive piston coupled with the valve body by the thrust rod,
wherein each valve body is movable by the respective drive piston such that the valve body sealingly seats with an edge of the respective inlet orifice.
