NOZZLE HOLDERS (MODELS: BIJET & QUADRIJET)
The BIJET double nozzle holder is mounted with a cone and a flat fan nozzle made of ceramic.
The QUADRIJET quadruple nozzle holder is mounted with two cone and two flat fan nozzles made
of ceramic.
Both nozzle holders have a nondrip valve which cuts the liquid flow once the pressure drops
to
10 psi, thus preventing them from leaking.

Positioning a nozzle:
- The proper position of the nozzle is at 90º
(vertical) in relation to the boom. To use the
other nozzle, just turn the nozzle holder (1) 180º.
Shutting a nozzle:
- Just turn the nozzle holder to set both nozzles
parallel to the boom (in the horizontal), 90° of
a turn.

Positioning a nozzle:
- Loosen the nut (1) with two turns. Position
the chosen nozzle and retighten the nut.
Shutting a nozzle:
- Loosen the nut (1) with two turns and
turn the nozzle holder to 45º. Retighten the
nut.
NOZZLES
The nozzles have the function to generate droplets and distribute them uniformly over
the area being sprayed.
Operating with pressure over that recommended by the manufacturer will decrease
the nozzle's life, besides increasing drift , environmental contamination and and changes
regarding the flow rate, angle and droplet size .
The nozzles used in this sprayer are made of ceramic, a material very resistant to wear
and chemical action.
The nozzles are mounted as shown in the figures below.

CONE NOZZLE:
This nozzle is fitted into the nozzle holder through a
screw cap, which fact allows to use it at high pressures.
FLAT FAN NOZZLE:
This nozzle is fitted into
the nozzle holder through a quick fitting cap for
more practicability in eventual maintenance,
which fact allows to use it at pressure of up
to 7 kgf/pol² (100 psi).
