The NIBCO 585HP (high-performance) lead-free ball valve, available in sizes 1/2” through 2”, features a patented laser-welded construction that creates an incredibly strong joint between the body and body-end pieces, eliminating a potential leak path, NIBCO explains. The weld allows for an increased pressure rating up to 1,000 CWP, up from the traditional 600 CWP ball valves. Other features include a reversible handle (designed with prefabrication in mind), triple-sealed stem, and a large packing nut, which is easily accessible as most adjustable wrenches will fit under the handle.
