SPRAY VALVE DAS 100 EV k. Via Ravizza, 30 36075 Montecchio Maggiore (VI) - ITALY Tel. 0039 0444 574510 Fax 0039 0444 574324 davtech@davtech.it www.davtech.it The spray valve DAS 100 EV is designed to obtain micro-spraying of various kind of fluid. Its threaded inlet allows the feeding of products of medium to high viscosity , such as greases and lubricating pastes. The valve allows to obtain uniform coverage of the areas without going to affect the surrounding parts. For this reason it' ideal to be mounted on robot, arms etc. The spray caps are available in various shapes depending on the effect required. FIELDS OF APPLICATION: > Grease micro-spraying > Lubricants micro-spraying > Primer micro-spraying > Vinilic glues micro-spraying FEATURES: > Fine adjustment of the flow rate > Needle and nozzle in stainless steel > Operation mode normally closed with safety spring > Micro-spray on parts with minimum size of 8-10 mm > Do not create mist or unwanted drips > Easy maintenance and cleaning of the valve.

AIR CAPS AND SPRAY NOZZLES Depending on the fluid, the spray nozzles are available in various diameters from 0.3 to 1.5 mm, while the air caps allow to obtain a round or oval spray pattern. DRIVE THE VALVE DAS 100 EV The valve DAS 100 EV is equipped with a solenoid valve, that with a 24 VDC feeding open the dispensing. The atomizing air, necessary for the spraying,have to be drived with another 3/2 solenoid valve with a precision pressure regulator mounted on the line. This allows to keep separate the timing of dosing and spraying, and allow to have the greatest possible results. Valve...
