Wafer type dual plate check valve is one type of non-return valve with two torsion springs added to each of pair valve plates,which close the plates quickly and automatically, preventing the mediums from flowing back. Wafer dual plate check valve can be mounted between the two pipes in both horizontal and vertical directions. Wafer type dual plate check valve has features of compact structure, light weight and bidirectional. Flowspec Luokai can manufacture the wafer type dual plate check valve in accordance with API594 with material of cast iron, ductile iron and bronze.
