4 Description of Function
4.1 Purpose of the Incomplete Device
The MINI Full-jet Valve VMS-08 is a pneumatically controlled application device for applying liquid media
such as oils or separating agents. The spraying process is generated by the control air and the material supply pressure and can be either an intermittent or continuous process.
The control air for opening will be supplied through a pilot valve (not included in scope of delivery) and will
not have a passage in the basic position. Once the pilot valve for the control air receives a signal, the front
area of the needle piston chamber will be flooded with air; this results in the needle piston pushing back
against the spring and opening the needle.
Now the material is discharged from the nozzle. If there is no signal for the pilot valve of the control air, the
needle will be pushed into the nozzle by the spring in the piston chamber and the spraying device is closed.
Needle function: opened by air pressure / closed by spring pressure.
Should the control air fail, the valve will be closed by the needle spring.
The spray medium is supplied to the valve via a pressured container or a pump.
4.2 Technical Data
Dimensions = ca. 64mm x 21mm x27mm (without nozzle)
Weight = ca. 65g
Control air pressure = 5 – 7 bar
Material pressure = max. 3 bar (without closing air)

5 Initial Start-up
5.1 Mounting and Installation
The spraying device can be installed in any position.
The distance of the nozzle to the application surface depends on the required spraying width. The larger the
distance of the nozzle to the application surface, the larger will be the spraying width of the material.
Make sure that the spraying device is secured fastened on the holder or in machine!
Intermitting processes can cause vibrations.
Machine vibrations to the valves and from the valves to the machine should be avoided in order to achieve a
clean and accurate application surface.
Vibrations of the valve caused by fast intermitting cycles require solid and tight installation. Machine
vibrations to the valves should be avoided.
5.2 Hose Mounting
Control air and material will be supplied to the spraying device via two separate connections. The following
markings are used:
Control air -open- (black)
Connection S : to 3/2-way magnetic valve (without closing air)
2x to 5/2-way magnetic valve (with closing air)
Material (transparent or white)
Connection M : to pressured container or pump
Please observe prior to initial start-up:
Turn on energy supply
Turn on supply for atomizer air, control air and material
Use control unit to start device
Check correct function and proper operation of device
Check if device operation stays within all pre-set parameters
After checking that the device is properly functioning, it can be employed with due regard to the guiding
safety and accident prevention directives.
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
IMPORTANT
The amount of material can be individually regulated via the regulating screw.
Right turn: decreasing material quantity
Left turn: increasing material quantity
Nozzle and needle can be damaged by wrong handling.
Only decrease the material flow (by a right turn of the regulating knob) if material is
discharged.
Do not turn the regulating knob further to the right after the nozzle is closed!
6 Operation
6.1 General Information
This device may 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
The valves can be controlled for intermittent or continuous use. According to the individual applica-
tion, 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, short conductions).
The VMS-08 usually works with a control air pressure of 5 – 7 bar.
During longer standstills the material can remain in the valve as long as it is under pressure and
does not have any contact with outside air.
Material and control air will only be used in a clean, filtered condition. Control air should be slightly
oiled when supplied to the spraying device.
The valves of the VMS-08 series usually operate with a control air pressure of 5 - 7 bar. In case high
material pressures are necessary, the safety regulations of the trade association must always be observed.
6.3 Adjusting and Setting
During longer standstills the material can remain in the valve as long as it is under pressure and does not
have any contact with outside air.
Turn on energy supply.
Turn on supply for atomizer air, control air and material.
Use the control unit to start device.
Check device for correct function and proper operation.
Check if device operation stays within all set parameters.
6.5 Turning off
Use the control unit to turn device off.
Turn off supply for atomizer air, control air and material.
Turn off energy supply.
