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.
