Civacon's 345 series butterfly valve in a 2 inch size, built with an aluminum body and a stainless steel disc rather than nodular iron. A 17-4 stainless steel stem and white nitrile seat complete the valve, which carries the same 45 psi rating and lug-style bolt pattern as the rest of the 345 line, and can replace 340, 500, and 890 series valves in service today.
