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 - Solid cone-shaped spray pattern with round impact area or cone-shaped spray pattern with square-like impact area for coverage of rectangular areas or spray zones - Spray angles: Standard – 43° to 91°, Wide – 112° to 120° - Uniform spray distribution from .08 to 7.4 gpm (.3 to 28 lpm) - Operating pressures up to 300 psi (20 bar) **Flow:** As the liquid enters the nozzle, it passes through an internal strainer and into the slotted core where the swirling begins. The swirling continues as the liquid passes through a disc. The breakup of the liquid occurs as it exits the orifice, producing a well-defined cone pattern. The drops are uniform in size and distributed equally throughout the spray pattern.
