Systems of this type are always used whenever the nozzle and air cap are exposed to extreme material build-up. This is why the system is fitted with an additional flushing valve. After the spray cycle a mix of air and cleaning agent is pressed into the circular gap between the nozzle and the air cap.
This is a small spray system with a material pressure tank, to apply about 210,000 dots (dots 5 mm in diameter) or 13,500 meters of lines (5 mm wide)
Simple operation, low maintenance n For dots of from 3 to 30 mm in diameter
A solenoid valve is used to trigger the spray gun. WALTHER PILOT can also deliver the controls, upon request.
We would be happy to provide planning and assembly services, right through to integrating the system into your assembly line.

When the marking process is finished, the solenoid valve is used to shut off the marking gun.
Use the solenoid valve to open the flushing valve for about 3 to 5 seconds. A mix of air and solvent cleans the area between the nozzle and the air cap.
Use the solenoid valve to close the flushing valve after flushing is finished.
Open the solenoid valve for about 5 seconds to dry the nozzle and air cap area.
Close solenoid valve; cleaning process is complete.
