North American  Ratio Regulator 7216-FIVES

Fives’ ultimate design of regulators allows for proper control of the combustion system fuel supply which is extremely important to optimize production and achieve the best efficiency of combustion equipment. Combustion systems are designed to run optimally at a certain fuel supply pressure.  Controlling that pressure over the entire operating range of the combustion system is extremely important. 

Fives provides a wide range of pressure reducing regulators, and associated pressure relief valves to choose that have been selected to provide ultimate pressure control for the many combustion system designs in the marketplace.

Fives ratio regulators accurately maintain a constant air/gas ratio over a wide range of firing rates in both nozzle-mix and premix gas burner systems.  Molded diaphragms ensure excellent tracking, repeatability, maximum flows, and superior turndown.
