DFDK Series Inline Duplex Filters 4568 psi up to 9 gpm Hydraulic Symbol DFDK QL L Ball Valve A DFDK QT T Ball Valve (sizes 33 or larger) A B B Features The DFDK Filters have a filter head of ductile iron and a screw-in bowl of cold-formed steel. The filter housings are designed to withstand pressure surges as well as high static pressure loads. The screw-in bowl or lid, allows the filter element to be easily removed for replacement or cleaning. A visual (pop-up), electrical, electrical/visual (lamp), or other electronic differential types of clogging indicators are available to suit each application. DFDK filters are available only with high collapse pressure elements since no bypass is provided. DFDK sizes 33 and above can be ordered with a T Ball Valve which can operate in mid position with both elements fully open and online in parallel.
