VUOTOTECNICA 070563NO

These solenoid valves have the same functions and structure as the previously described ones. Their distinctive feature is a bistable impulse solenoid valve activated by a built-in low absorption electric coil which, at a simple electric impulse, exchanges the shutter position even in absence of electricity, until it receives a new impulse of opposite polarity. For this reason, they can only be supplied with DC electric coils. They are particularly recommended in all those cases that require a safe connection to the vacuum source, even in absence of electricity. The electric coil of the solenoid pilot valve is fully plasticised plasticised with synthetic resin, tight execution, insulation class F (up to 155 °C) compliant with VDE standards, with 3 mm 2-terminal electrical connections in compliance with EN 175301-803 (ex 43650)-C. Protection degree IP 54; IP 65 for inserted connector. Available for voltages of 12-24V/CC. Allowed tolerance on the voltage nominal value: ±10%. Maximum electric power: 1 W The connector can be rotated by 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. The push-button device for their manual activation cannot be installed on these solenoid valves.
