TANKS FOR FLUID FEEDING
The PT series DAV Tech tanks are ideal to feed in the best way the valves
DAS 50 and DAS 50N. They are available in 3 sizes 2, 5 and 10 liters and in
different variations. Made of mirror polished stainless steel and aluminum,
all tanks can be equipped on request with an electrical minimum level sensor.
DRIVE THE VALVES DAS 50 AND DAS 50N
The valves DAS 50 and DAS 50N have to be drived with a 3/2 solenoid valve, timed by the customer. 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.
EXTENSIONS FOR VALVES DAS 50 AND DAS 50N
The valves DAS 50 and DAS 50N may be provided with extensions of different lengths. 15mm, 30mm and 50mm are
standard sizes, and upon request can be constructed with higher lengths or different positions of the spraying holes.

3 INSTALLATION
3.1 Mounting in the machine
The DAS 50 / DAS 50N valve must be mounted using the fixing plate
on the valve.
A good valve fixing on the machine must be guaranteed, stable
without vibration and with good accessibility for adjustment, cleaning
and maintenance.
3.2 Drive the valve
The DAS 50 / DAS 50N spray valve must be operated by two separate solenoid valves; a 3/2 way for the pilot (black
tube) and a 3/2 way for the nebulization (blue tube).
The operating pressure must be between 4 ... 6 bar.
Additional air pressure between 0.1 ... 3 bar.
3.3 Fluid connections
The valve must be connected to a fluid supply unit (pressure drum or diaphragm pump).
The material pipe is the transparent 6x4 diameter.
