Gas/Air Ratio Regulator GIK

GIK regulators hold constant gas/air ratios on nozzle mix and premix burner systems. They are designed and built with precise internal tolerances, and they provide highly accurate, repeatable pressure tracking over the turndown range of the burner system. They are suitable for natural, LP, and clean, dry bio-gas. Special GIK models are available for controlling air pressure.

Features

• For maintaining constant gas/air ratios
• Cross-connected operation with modulating or high-low control of nozzle mix burners
• Zero regulator operation for premix burners
• Precise pressure regulation over wide turndown ranges
• Low maintenance
• Valve seat design for consistent low-fire repeatability
• Balanced double diaphragm design allows regulator to operate over a wide range of inlet pressures while minimally affecting outlet pressure
• CE certified models available

	Applications Click on images for close-up view. Nozzle Mix Burner with High/Low Control including Pulse-firing When used as cross-connected regulator for nozzle mix burners, GIK regulator provide outlet gas pressure at a 1:1 pressure ratio with air loading. For leaner or richer low fire ratios, the bias spring can be adjusted to provide an outlet pressure up to 1.2" WC (3 mbar) higher or lower than the loading pressure. Nozzle Mix Burner with Modulating Control The cross connection line should be no smaller than ¼" pipe or ⅜” OD tubing, as short and with as few bends as possible. Premix Burners If burner is sealed in and combustion chamber pressure is other than zero, connect vent to combustion chamber. Otherwise leave it open to atmosphere.
