These direct-drive valves have been specially designed for vacuum and are normally closed. They are composed of an anodised aluminium body, where the connections and the passage mouths are located, and of an actuator which is activated by an electric coil. The solenoid pilot valve shutter in NBR nitrile rubber or Vulkollan® is an integral part of the actuator mobile core.

Both the mouths of the two-way solenoid pilot valves have the same size, while those of the three-way ones have a
1.5 mm outlet diameter, obtained through the tube. The very low reaction time allows carrying out a very high number of cycles per minute.

The standard electric coil is fully plasticised with synthetic resin, tight execution, insulation class F (up to 155°C) compliant with VDE standards, with 6.3 mm three-terminal electrical connections in compliance with EN 175301-803 (ex DIN 43650).

Protection degree IP 54; IP 65 with connector inserted.
Tolerance permitted on the nominal voltage value: ±10%.
Maximum absorption: 8 V.A. with AC and 6.5 W with DC.
The electric coil can be rotated 360°.
The connector can be rotated 180° on the coil and can be supplied, upon request, with LED lights, anti-interference circuit and/or with protection devices against overvoltage and polarity reversal.
