Description

Description:

  • The NIBCO® cast iron sliding disc check valve is wafer style and lead-free, designed to fit between standard flanges for easy installation without requiring additional space for a bolted bonnet. Its spring-actuated design provides reliable backflow prevention, automatically closing when fluid reverses direction. The spring return also significantly reduces noise during operation, making it well-suited for commercial and industrial water applications where quiet performance matters.
  • This NIBCO® check valve may be installed in horizontal positions or in vertical applications with upward flow. For proper engineering and installation guidance, refer to NIBCO® technical data sheets, chemical resistance guides, and catalogs. NIBCO® check valves are backed by the NIBCO® 5-year 125% limited warranty.
