Audited Supplier ELIO gas air ratio regulator VRG is designed for constant ratio control of gas and air for combustion, it regulate the gas pressure upstream of gas burner on installations without preheated combustion air, it used for modulating controls. the gas air ratio regulator is activated by the pressure of the combustion air line, it regulates the gas outlet pressure in the ratio 1:1 to the air control pressure, the burner capacity is varied with the aid of the air control valve
furnace pressure fluctuations have the same effect on gas and air throughtout, thus meaning that the gas air mixture does not change
the low fire rate can be seted by adjusting the regulator spring
in the case of high/low control, the spring should be fully relaxed. the min flow flows only through the bypass
the setting at high fire is performed via valves on the burner
With spring for compensating for the weight of the diaphragm assembly in the case of modulating control
Gas air ratio regulator with inlet pressure compenation diaphragm and zero shutoff
