Flowserve Atomac check valve ARK2

Flowserve Atomac ARK2 check valve

The fully PFA-lined FLOWSERVE ATOMAC swing check valves are ideal for use in highly corrosive applications and can replace swing check valves made from exotic alloys due to the universal chemical resistance of the fluoropolymer lining. These valves can be used in horizontal and vertical installations due to the special design of the hinge pin, which enables the disc to achieve a seal without support of any system pressure.

The ATOMAC ARK2 eliminates a potential leak path of conventional 3-piece and 2-piece designs with a seat face integrated into the body liner to seal against the disc in the closed position. The disc can swing freely within the piping system without interference with the diameter of the connecting pipe.  Please see our datasheet for detailed information.
