Servo-controlled 3-way vacuum solenoid valves
The 3-way vacuum solenoid valves in this series are 2-position valves with pneumatically servo-controlled conical shutters.
They can be used normally either closed or open.
They are composed of an anodised aluminium body, two Vulkollan® shutters assembled onto a stainless steel stem, a membrane for servo-control made with special compounds and a thrust spring for the shutter return; an actuator activated by an electric coil managed the compressed air supply.
These valves allow reducing frictions and internal dynamic stresses to the minimum. The result being a high response speed and a guarantee of long lasting duration. 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 3-terminal electrical connections in compliance with EN 175301-803 (ex DIN 43650).
Protection degree IP 54; IP 65 for inserted connector.
Allowed tolerance on the voltage nominal value: ±10%.
Max. absorption: 20 V.A. in c.a. e 18 W in c.c.
The electric coil can be rotated by 360°.
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. 3-way vacuum solenoid valves are usually used for intercepting vacuum on feeders and cup stackers, robots, sheet feeders, sack openers and in all those cases where a quick response is needed between suction and the air inlet into the circuit, for a quick restoration of the atmospheric pressure.

Servo-controlled 3-way vacuum solenoid valves with two electric coils
These solenoid valves have the same function and the same structure as the previously described three-way valves.
Even their structure is the same, but their distinctive features are the two coils that with a simple electric impulse exchange the shutter positions and keep them in this position till the next impulse even in absence of compressed air at the servo control and of electric current.
This is the reason why their use is especially recommended in all those cases requiring maximum connection security at the vacuum source, even in the absence of electrical and pneumatic power supply.
The standard electric coils are fully plastic-coated in synthetic resin, watertight, insulation class F (up to 155°C) as per standard VDE, with 6.3 mm three-terminal electrical connections for connectors 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 - 20 V.A. with AC and 6.5 - 18 W with DC.
The electric coils can be rotated 180°. The connectors can be rotated 180° on the coils and can be supplied, upon request, with LED lights, anti-interference circuit and/or with protection devices against overvoltage and polarity reversal.

Direct drive 3-way vacuum solenoid valves
These direct drive three-way, two-position vacuum solenoid valves feature conical shutters servo-controlled by the vacuum.
They are normally closed as standard, but they can be supplied normally open upon request.
They are composed of an anodised aluminium body where the connections are located, two silicone shutters assembled onto a stainless steel stem and a membrane in special reinforced compound. An actuator activated by an electric coil manages the vacuum at the servo-control. The operating principle of these solenoid valves is based on the pressure differential between the vacuum pump or generator and the pressure of the suctioned air.
By addressing this “differential pressure” to the servo-control via the actuator, the shutters can be controlled without compressed air or springs.
Due to their operating principle, they are not recommended on plants with rough vacuum levels (below 850 absolute mbar, equal to 15 % vacuum).
The lack of springs, frictions and internal dynamic stresses favours a high response speed and guarantees long lasting operation.
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: 20 V.A. with AC and 18 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.
The solenoid valves in this series, along with the uses described for the 07 .. 11 series, can be used on plants with no compressed air.
The solenoid valve must be always chosen according to the flow rate and, therefore, to the vacuum pump or generator suction connection.

Servo-controlled 3-way vacuum solenoid valves with bistable impulse solenoid pilot valve and with low absorption electric coil
These solenoid valves have the same function and the same structure as the previously described three-way valves.
Even their structure is the same; what differentiates them are the bistable impulse solenoid pilot valve powered by a low absorption fitted electrical coil which, with a simple electrical impulse, exchanges the shutter positions and keeps them there even in absence of electricity, until it receives a new impulse of opposite polarity. For this reason, they can only be supplied with direct current electric coils.
Their use is especially recommended in all those cases requiring maximum connection security at the vacuum source, even in the absence of electrical power supply.
The electric coils of the solenoid pilot valve are fully plastic-coated in synthetic resin, watertight, insulation class F (up to 155°C) as per standard VDE, with 3 mm two-terminal electrical connections for connectors in compliance with EN 175301-803(ex DIN 43650) – C. Protection degree IP 54; IP 65 with connector inserted.
Available for voltages 12-24VDC.
Tolerance permitted on the nominal voltage value: ±10%.
Maximum electric power: 1 W
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.
The push-button device for their manual activation cannot be installed on these solenoid valves.
