C - Suction valve
With this valve you can select suction from main tank (for spraying) or from rinsing tank.
D - External Filling Device valve (optional)
This valve is used, when filling from an external tank or reservoir.
Activating the valve starts/stops the filling process. Note that the suction valve must be closed for maximum filling capacity.

ATTENTION! If a valve is too tight to operate - or to loose (= liquid leakage), the valve needs to be serviced. Please see
the section ‘Maintenance’ for further information.
Control Unit
The sprayer is equipped with an EVC control unit.
EVC Control Unit
The system is based on EVC - Electrical Valve Control. The ON/OFF is
linked to the section valves (one valve for each spray boom section),
which results in a quick response to ON/OFF. The operating unit is of
modular design, and it is electrically controlled by a remote control box.
The section valves are fitted with a constant pressure device and a
pressure drop line.
These features allows the operator to shut off individual boom sections.
The unit has a built-in HARDI-MATIC system. This system ensures a
constant liquid volume per hectare (l/ha) when driving forward at
varying speed within the same gear, as long as the number of PTO
revolutions are kept between 300-600 rpm.
