Part number DC501-2 is the 2 inch ARI DC-501, the largest size of this double check valve assembly (DCA), which runs from 1/2 to 2 inch and is a current model. The body and shutoff valves are a composite plastic material; ARI calls it a non-corrosive thermal resin and pairs it with stainless steel screws and springs. Two independent capsulated check valves, each spring loaded and easily replaced, do the work, and the ends are NPT threaded. ARI points to irrigation systems, water handling and potable water lines as applications.
