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.

As these valves have no friction or internal dynamic stresses, the result is a high response speed and a guarantee of long lasting operation.

With 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. Due to this feature, their use is particularly advisable in all those cases where it is required the maximum guarantee of connection to the vacuum source, also in absence of electric or pneumatic feed.

Working pressure: from 0 to 3 bar abs.

Pressure at the servo control: from 4 to 8 bar (g).

The electric coils are standard, completely plasticized in synthetic resin, tight execution, insulation class F (up to 155°C) electrical connections by means of a plug with clamping screws.

Acceptable tolerance on the nominal value of the voltage ± 10%.

Max. input: 7,5 ÷ 17 V.A. with A.C. and 5 ÷ 10 Watt with D.C.

Coils may be rotated through 360°.
