DOXI fully lined swing check valves are ideal for use in highly corrrsive applications due to the universal chemical resistance of 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 with out support of any system pressure.
2- Piece design eliminating a potential leak path with a seat face integrated in the body liner to seal against the disc in the closed position.
The disc can swing feely within piping system without interference with the diameter of the connecting pipe.
