General Information

Description

  • Quick-connect nozzles reduce maintenance time – bodies remain on pipe/header
  • Save on nozzle replacement costs – bodies can be reused, only spray tips are replaced; tips fit on male or female bodies
  • Hollow cone spray pattern with a circular impact area
  • Excellent atomization at relatively low pressures
  • Spray angles: Standard – 13° to 114°, Wide – 130° to 140°
  • Uniform spray distribution from 3.6 to 4,920 gph (13.2 to 17,760 lph)
  • Operating pressures up to 400 psi (25 bar)
  • Orifice inserts, cores and strainers are easily removed for inspection or cleaning
  • TN versions provide very fine atomized sprays using liquid pressure alone; compressed air not required
  • Spray angles: Standard – 43° to 91°
  • Uniform spray distribution from .82 to 184 gph (3.1 to 701 lph)
  • Operating pressures up to 2000 psi (140 bar)

Flow

As the liquid passes through the nozzle, it is forced to pass through slots in the orifice. These slots make the liquid spin in a circle at a high speed as it exits the orifice, creating the hollow cone pattern.
