We are the first-class HAGO agent in China since 1998.HAGO is a professional world-wide famous nozzle manufacturer in USA. We deal every type of Hago products. Pursuing advanced technology and innovation ,each HAGO nozzle has its own unique feature which other brand nozzle can not match to.For examples,By-passing oil burner nozzles maintain steady spray angle across the entire turndown range while other brands often vary as much as 15 degrees from open to closed by-pass line. Ecovalve nozzle anti-drip valve produces a razor sharp cutoff of the spray at burner turndown.No-more after-drip caused by pressure dissipation or air bubbles and after-drip cased by heat expansion of the oil is tremendously reduced ,as well.
