Description

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