Nibco S-580-70-NS-112 Bronze Ball Valve 1-1/2 in

Product Description

The NIBCO S-580-70-NS-112 is a bronze ball valve designed for quarter-turn (90-degree) open-to-close operation. It features the NIBSEAL insulated handle, which eliminates condensate formation on the valve body — a practical advantage in HVAC and chilled water applications. Built for commercial and light industrial service, this valve handles hot and cold domestic water, low-pressure steam, and hot water heating systems. Licensed plumbers and HVAC technicians are the primary installers. The 1-1/2 inch size suits a wide range of piping systems where a reliable shutoff or isolation point is required.

This valve is suited for commercial mechanical rooms, light industrial process lines, and building HVAC systems. Typical applications include chilled water supply and return, domestic hot and cold water distribution, low-pressure steam service, and hot water heating loops. The NIBSEAL insulated handle makes it especially practical in environments where condensate on valve components is a concern, such as cooling systems and refrigeration-adjacent piping.
