MRO

Hauck MRO oil-air ratio regulators are designed to serve as the essential control device in a cross connected oil-air delivery system. They support applications requiring 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 Hauck MRO ratio regulator can be used with No. 1 through No. 6 fuel oil. It is suitable for use with oil temperatures up to 270ºF (132ºC). Model Oil Connection Oil Capacity LPH NPT DN Min. Max. MRO 105 1/2 15 2.8 189 MRO 107 3/4 20 7.6 379 MRO 207 3/4 20 23 1760
