If the pause time is a multiple of the spray time, the valve must be sprayed free in a separate location
or the spray valve should be operated several times to optimize the application.
After standstills of 15 min. and more, the valve must be sprayed free by pressing the switch 3 to 5
times.
The application can be controlled as intermitting or continuous. Depending on the individual use, the control
pressure has to be adjusted to the set switching frequency on the one hand and to the higher or lower
material pressures on the other. Under appropriate operating conditions (material pressure, control pressure,
needle stroke, and short supply lines) a total of 50 strokes per second can be reached.
IMPORTANT
A device-specific set-up is required for an optimum adjustment of the application image.
Basic results from lab tests can be used. Of course, these may have to be adjusted for the
individual device. The parameters nozzle size, opening time, opening stroke, material pres-
sure and if required, also temperature have to be combined.
For longer standstills, the material can remain in the valve, if it remains under pressure (no contact to outside
air).
