The 585HP is on the cutting edge of manufacturing technology, ease of installation, and highest quality standards. The Classic Ball Valve has been completely rethought and redesigned to enhance the user experience and incorporate advances in assembly technology. NIBCO has created the most advanced commercial ball valve on the market today. The valve is laser-welded to create an incredibly strong joint between the body and body-end pieces, eliminating a potential leak path. The weld allows for an increased pressure rating of 1,000 psi, up from the standard 600 psi.
