Oil-Air Ratio Regulators MRO

Hauck MRO oil-air ratio regulators are designed to serve as the essential control device in a cross connected oil-air delivery system.

The MRO regulators support applications requiringm wide turndown and/or low flow rates and repeatability. The MRO is engineered to function properly over a wide range of air pressures and may be used on either single or multiple burner applications. A constant oil pressure is required at the inlet of the regulator. The MRO provides an automatic and simple means of maintaining this ratio even at extremely low flow rates. Features & Benefits: • Accurate and repeatable low flow rate sensitivity • Wide turndown capability • Easy to maintain • Wide capacity range • Provides automatic and simple method of maintaining air/oil ratio • Requires constant oil supply at 45 - 65 psig (310 - 450 kPa) • Rugged modular construction • Overpressure safety relief valve • Handles No. 1 through No. 6 fuel oil.
