TANKS FOR FLUID FEEDING

The PT series DAV Tech tanks are ideal to feed in the best way the valve 
DAS 90. 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 VALVE DAS 90

The valve DAS 90 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.

We reserve the right to modify at any time, without notice, the specifications, dimensions and weights in this datasheet. The illustrations are not binding.

3 INSTALLATION 

3.1 Mounting in the machine

The DAS 90 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 90 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 5 and 7 bar.

The nebulization between 0,1…2.5 bar.

The atomizing air must be activated before and closed after the operating air, this to prevent the glue from dirtying the 

nozzle and the cap.

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.

INSTALLAZIONE

3.1

Montaggio della Valvola

La Valvola DAS 90 deve essere montata 
utilizzando la piastra di fissaggio presente 
sulla Valvola.

Deve essere garantito un buon fissaggio della 
Valvola sulla macchina, stabile senza 
vibrazioni e con una buona accessibilità per 
la regolazione, la pulizia e la manutenzione.

3.2

Azionare la Valvola

La Valvola spray DAS 90 deve essere azionate da due elettrovalvole 
separate; una da 3/2 vie per il pilotaggio (tubo nero) e una da 3/2 vie per 
la nebulizzazione (tubo blu). 
La pressione di azionamento deve essere compresa tra 5 e 7 bar.
La pressione di nebulizzazione tra 0,1…2.5 bar.
L’aria di nebulizzazione deve essere attivata prima e chiusa dopo l’aria di 
azionamento, questo per impedire che la colla possa sporcare l’ugello e il 
cappuccio.

3.3

Collegamento del materiale

La Valvola deve essere collegata ad un gruppo di alimentazione colla 
(fusto sotto pressione o pompa a membrana).
Il tubo del materiale è quello trasparente di diametro 6x4.
