5 Initial Start-up
5.1 Mounting and Installation
The valves can be installed in any position. The distance to the application are depends on the desired
application image.
Vibrations of the valve caused by fast intermitting cycles require solid and tight installation. The device
comes with two borings of 5mm diameter which have been designed for a solid mounting. Excessive ma-
chine vibrations to the valves should be avoided:
5.2 Hose Mounting
Two functional hoses will be connected as follows:
1.
Control air (black) to
M5-connection -
Pos. 11.0 „control air“
3.
Material (transparent)
1/4"-connection - Pos. 13
.0 „material“
5.3 Raster-Needle Sensor
Optionally, you can use a raster-needle lock with a pre-installed, inductive proximity switch. It will release a
signal when the needle piston with the needle is open. This will help you in digitally monitoring the status
„nozzle open“.

The stroke must be open at least 10 raster steps, in order to guarantee correct functioning of the
proximity switch!
5.4 Adjusting the Incomplete Device
The amount of material can be regulated via the stroke adjustment of the needle (7.0). A left turn of the regu-
lating knob increases the material amount. A fine precision thread affects a needle rise that results in an
adjustment of 0.5 mm with each turn of the adjusting knob.
IMPORTANT
Do not turn the regulating knob further to the left if no more stops are noticeable while turn-
ing it! The maximum fluid outlet has been reached!
Further turning will damage the regulating screw!
IMPORTANT
Nozzle and needle can be damaged by wrong handling. Only decrease the material flow (by
a right turn of the regulating knob) if material spills out. Do not turn the regulating knob fur-
ther to the right after the nozzle is closed!
