Vacuum Valves - Automatic

These vacuum valves are of the three-way type, with two positions and with pneumatically controlled conical valves. They can be used either normally closed or normally open.

[ 2- and 3-way vacuum solenoid valves ]

Developed specifically for vacuum, they are direct-acting, normally closed.

The two-way solenoid valves have considerably large orifices compared to their sizes. The three-way ones, although they have different passage orifices, they all have a fixed outlet, through the 3 mm. tube.

[ 2-way vacuum solenoid valves ]

Of a new design, with small dimensions, high volumetric efficiency and high response speed at any vacuum degree. The DDN vacuum solenoid valves are a two position, direct acting normally closed valve.

The body is made of brass with Viton seals. Working pressure: from 0 to 1,5 bar absolute.

[ 3-way vacuum solenoid valves ]

The three-way vacuum solenoid valves of this series are with two positions, with pneumatically servo controlled conical valves, normally closed or open. The body is in anticorodal aluminium, the valves and the membrane of the servo control are in Vulkollan.

[ 3-way vacuum double solenoid valves ]

These solenoid valves have the same function and structure as the three-way servo controlled ones.

The feature that differentiates them are the two solenoids which, with a simple electrical impulse, exchange the valves position and keep them in this position until when there is a new impulse, and this also in absence of compressed air at the servo control and of electric current too.

[ 3-way vacuum solenoid valves ]

The three-way vacuum solenoid valves of this series are direct-acting, with two positions, with servo controlled conical valves and normally closed. Upon request they can be supplied normally open. The body is in anodized aluminium, the valves are in silicone and the servo control membrane is in nitrile rubber.
