6 Operation
6.1 General Information
This device will only be operated if the safety-related equipment is permanently effective and not suspended
during operation or altered in its intended effectiveness.
6.2 Operation Instructions / Operating Conditions
CAUTION
Never point the jet at people. The wearing of eye protection is strongly recommended.
The spraying process can create noise depending on the air and fluid pressures used.
Ear protection should be worn, if required.
WARNING
Danger caused by flammable, harmful fluid. Always follow the safety instructions on the
container or the safety data sheet for the fluid.
The valves of the
VMS-05 Special Design
series generally operate with a control air pressure of 6 bar and
material pressures of up to 30 bar.
IMPORTANT
Accident prevention directions will be
strictly
followed when applying high material
pressures. Please strictly follow the following instructions when planning and
constructing application systems.
The valves are able to perform contact-applications or also contact-free applications. The valves can be
controlled for intermittent or continuous use. According to the individual application, the control air must be
adjusted to the operating cycles and to the higher or lower material pressures. 40 tacts per second can be
reached under appropriate operating conditions (material pressure, control air pressure, needle stroke, and
short conductions).
The amount of material can be regulated via the stroke adjustment of the needle. A left turn of the locking
screw increases the material amount. A fine precision thread affects a needle rise that results in an adjust-
ment of 0.5 mm with each turn of the adjusting knob.
IMPORTANT
The base for an optimum setting of the application image is a device-specific
adjustment. Basic values from lab tests can be used as references. However these
have to be adjusted individually. Parameters such as nozzle size, opening time,
opening stroke, material pressure and maybe also temperature have to be combined.
For longer times of standstill, the material can remain in the valve, if it remains under pressure (no contact to
outside air).
