Nozzles
Despite being the most important component for accurate uniform spraying application, nozzles are often neglected and
abused.
Nozzle flow rate depends on effective orifice size and pressure. Spray tip manufacturers have supplied tables of nozzle
application rates at various pressures, for the best results it is recommended that you follow these guidelines.
The rule of thumb is that as you increase the pressure to your unit the average droplet size decreases. Normally with
conventional open boom sprayers large droplets are used to control drift but large droplets can roll off plants without
sticking. With the
Windfoil covered spray system you will be able spray with smaller droplets, increase coverage and
not worry about drift.
The spray patterns must overlap for even coverage but should not interfere with one another. Nozzles are set at a 10°
angle so that one edge of its pattern will be just behind the edge of its adjacent spray pattern, evading interference with
each other.
Typically as a tip wears the spray pattern distorts output volumes usually increase and the droplet characteristics
change. Recalibration may correct for output changes, but cannot correct for spray pattern changes or the drop size
generated.
Caution: When spraying next to a flower bed, do not spray over the turf edge as the spray will go
under the curtain and onto the flowers.
Diaphragm Check Valve Nozzle Bodies
Diaphragm check valves close at approximately 15 psi (1 bar) to prevent excessive dripping. Should the cap on the
valve loosen or the check valve diaphragm become misaligned, the body may leak. Stop the leak by, tightening the
check valve cap or remove the cap and inspect the seal for damage or improper assembly.
To check for defective check valves when the spraying stop control has been actuated, the volume that drips from each
nozzle should not exceed 2ml timed over a 5 minute period. The measuring is to start 8 seconds after the flow to the
spray boom is shut off.
Nozzle caps are attached by engaging the cap and turning clockwise about a third of a turn. Self-aligning caps have a
slot to align the tips. Ensure that the tips fit down into the slotted hole before installing caps on the diaphragm nozzle
body assembly with the tip screens.
Non-aligning caps are also available for special tips.
Calibration
As a tip wears recalibration may be required. Collect the output from each nozzle for 60 seconds, using an accurate
measuring cup. Use clear water for all testing. Record the output from each nozzle. Replace nozzles that are more than
5% above or below the average reading, or has a visibly distorted pattern.
