Advantage
1.Face-to-face dimensions for KATA Dual Plate Wafer Check Valves are about one fourth of a Swing Check Valve. 
2.Weight is as little as about 20% of the corresponding Swing Check Valve due to the compact design. 
3.Dual Plate Wafer Check Valves have a spring design to close valves more efficiently when the back flow occurs to reduce the water hammer. 
4.These valves have the lower pressure drop than Swing Check Valves because of little friction resistance. 
5.Dual Plate Wafer Check Valves are less expensive than Swing Check Valves because of the lightness and compact design. These valves are also easier and less expensive to install and maintain because of fewer piping supports and easy handling for installation. 
6.Because Dual Plate Wafer Check Valves are flangeless, they are installed between flanges. 
7.Normal installation method for horizontal flow is with the hinge pin in vertical position. 
8.Installation is available for both horizontal and vertical piping.
