Operation
Spray Nozzles
The spray nozzles have an outlet at each end
but only the jet that is flipped to the outward
facing position is “on”. This facilitates easy
changing between jets of different sizes, for
example, when requiring different application
rates to suit concentrated and diluted spraying.
Individual nozzles can be turned off when not
needed by flipping the nozzle 90 degrees so
that neither of its jets is facing outwards.
Nozzle direction can be adjusted by loosening
the attaching nut and angling the nozzle.
The nozzles include a non-drip valve, which
closes when the pressure drops below 1 Bar.
Nozzle Alignment
The Oktopus sprayer is assembled at Silvan
with the air ducts and modules placed in the
standard positions. If their position should be
changed, make sure that the jet is spraying
into the air stream and not fouling on the
diffuser as shown below.
HCC Hollow Cone Ceramic Jets
HCC hollow cone ceramic jets produce a
superior droplet spectrum and are fitted to both
sides of each nozzle body.
The HCC components fit the standard nozzle
body and use the standard nozzle cap.
Nozzle output can be varied by fitting different
size ceramic jets. Refer to the HCC Jet Chart on
page 13.
Due to the ceramic cores of HCC nozzles, they
normally have a long wear life and require little
maintenance other than regular checking and
cleaning. The spray pattern should be observed
periodically against a dark background to detect
signs of wear, which will be indicated by a
streaky or broken pattern. If worn nozzles are
detected, then the full set of nozzles and gaskets
should be replaced.
