6 Operation
6.1 General Information
This device may only be operated if the safety-related equipment is permanently effective and not suspend-
ed during operation or altered in its intended effectiveness.
6.2 Operating Instructions / Operational Requirements
CAUTION
Do not point the jet at people. The wearing of eye protection is strongly recommended.
The valve must not be operated without a nozzle
– it could be destroyed!
WARNING
Danger caused by flammable, harmful fluid. Always follow the safety instructions on the
container or the safety data sheet for the fluid.
According to the individual application, up to 400 tacts per second can be reached under appropriate
operating conditions (material pressure, medium, length of hoses). The valve works starting with an opening
time from 400µs upwards. The opening time (in real time) must correspond with the theoretical value, in
order to enable constant opening and closing.
IMPORTANT
A plant-specific setting is required for an optimal adjustment of the application pattern.
Starting values from laboratory tests can be used as a basis. However, these may
need to be adjusted for the specific plant. A combination of the following parameters is
necessary: nozzle size, opening time, opening stroke, material pressure and tempera-
ture (if applicable).
It is harmless to leave fluid in the valve during longer standstills if system stays under pressure (no
connection to outside air).
