During the spraying process, the spray pump (H) draws the spraying fluid from the
main tank (7) via the switching valve (C), the selection valve (A) and the suction
filter (9). The spraying fluid is then pumped to the nozzles via the diverting valve
(D) and the pressure filter (3).
The control valve (2) can be used to control the metering of the distribution rate.
The control valve is operated by the control unit and allows the spraying fluid not
required by the nozzles to flow into the agitator (5) and/or into the suction circuit of
the pump via the agitator regulator (E).
If automatic metering is switched on in the control unit, the metering proceeds de-
pending on the travel speed.
The agitator intensity is set with the agitator control (E). The permanent circulation
of the spraying fluid in the agitator circuit ensures constant mixing and concentra-
tion of the spraying fluid.
The flowmeter (4) measures the complete volumetric flow to all nozzles.
The pressure sensor (23) determines the spray pressure. The flush valve (F) on
the pressure filter (3) allows you to adjust the flushing intensity of the pressure fil-
ter.
The pressure control valve (17) directs the spraying fluid to the agitator (5) when
the system pressure is exceeded.
When the nozzles are switched off, the part-width section valves (20) close. The
spraying fluid flows through the central bypass valve (21) into the agitator (5).
