The Nibco cast iron automatic steam stop-check angle valve is designed for steam systems with boilers installed in tandem. The steam stop-check design prevents boiler flooding by automatically closing when steam and condensate begins to back up. These valves are also used to isolate boilers in a steam system. The valve is Class 250 flanged iron body and bronze mounted trim (IBBM). The Nibco steam stop-check angle valve has flanged end connections for ease of installation. This valve features renewable seat and disc. The bolted bonnet makes the valve convenient to maintain. Nibco valves are backed by the Nibco 5-years 125% limited warranty.
