Conbraco Industries 10-616-10 Hot Water High Capacity Pressure Relief Valve

The Conbraco Industries 10-616-10 is a high-capacity hot water pressure relief valve engineered for demanding hydronic heating and hot water system applications.

  • Inlet connection: 1-1/4″ Female NPT for easy in-line installation
  • Outlet connection: 1-1/2″ Female NPT for unrestricted discharge flow
  • Designed specifically for hot water heating system service
  • Heavy-duty construction for long service life in high-demand environments
  • Automatic pressure relief opens to protect system components from overpressure damage
Application

The 10-616-10 is the go-to solution for protecting commercial and industrial hot water boilers, storage tanks, and hydronic heating systems. The high BTU capacity and oversized connections make it well-suited for high-output boiler plants, large-scale hydronic systems, and any application where standard-capacity relief valves fall short. The 50 PSI set point aligns with common commercial hot water system operating parameters, providing a reliable safety margin without nuisance discharge.
