Servo-controlled 3-way vacuum solenoid valves

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 normally be used either open or closed.
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: 16.5 V.A. in c.a. e 16 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. They can be supplied upon request with an SM device for manually opening and closing the solenoid valves already installed.
Technical features
Working pressure: from 0.5 to 3000 mbar abs.
Servo-control pressure: see table
Temperature of the sucked fluid: from -5 to +60 °C

Servo-controlled 3-way vacuum solenoid valves with two electric coils

Servo-controlled 3-way vacuum solenoid valves with two electric coils

These solenoid valves have the same function and the same structure as the previous ones.
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.
For this feature, they are especially indicated in all those cases which require a safe connection to the vacuum source, even in absence of electric or pneumatic supply.

Direct drive 3-way vacuum solenoid valves

Direct drive 3-way vacuum solenoid valves

These direct drive 3-way, 2-position vacuum solenoid valves feature conical shutters servo-controlled by the vacuum.
As a standard they are normally closed, but they can be supplied normally open upon request. They are composed of an anodised aluminium body where the connections are located, two silicon 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 sucked 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 low vacuum levels (below 850 mbar abs., equal to 15 % of 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 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: 16.5 V.A. with AC and 16 W with DC.
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.
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. They can be provided, upon request, with SM device for manually opening or closing the solenoid valve already installed.
The solenoid valve must be always chosen according to the capacity and, therefore, to the vacuum pump or generator suction connection.
Technical features
Working pressure: from 0.5 to 850 mbar abs.
Temperature of the sucked fluid: from -5 to +60 °C

Servo-controlled 3-way vacuum solenoid valves with bistable impulse solenoid pilot valve and with low absorption electric coil

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 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.
Technical features
Working pressure: from 0.5 to 3000 mbar abs.
Servo-control pressure: see table
Temperature of the sucked fluid: from -5 to +60 °C

Direct drive 3-way vacuum solenoid valves with low absorption electric coil

The direct drive 3-way vacuum solenoid valves of this series feature two positions with conical shutters servo-controlled by the vacuum.
As a standard they are normally supplied closed, but upon request they can also be provided as normally open.
They are composed of an anodised aluminium body where the connections are located, two silicon shutters assembled onto a stainless steel stem and a membrane in special reinforced compound. A solenoid pilot valve activated by a built-in electric coil manages the servo-control vacuum. The operating principle of these solenoid valves is based upon the pressure differential between the vacuum pump or generator and the pressure of the sucked air. By directing this differential pressure to the servo-control via the solenoid pilot valve, it is possible to control the shutters with no need for compressed air or springs.
Due to their operating principle, these solenoid valves are not recommended for low vacuum level plants (below 850 mbar abs., equal to 15 % of vacuum). The absence of springs, frictions and internal dynamic stresses favours a high response speed and guarantees a long lasting operation.

Protection degree IP 54; IP 65 for inserted connector.
Available for voltages of 12-24V/50-60Hz and 12-24V/CC.
Allowed tolerance on the voltage nominal value: ±10%.
Maximum electric power: 2 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. A push-button device built-in the solenoid pilot valve allows the manual opening and closing of the solenoid valve.
The solenoid valves of this series can be used in almost all the cases described for the 07 .. 11 series, and also on plants with no compressed air. The solenoid valve must always be chosen according to the capacity and, therefore, to the vacuum pump or generator suction connection.

Syphon filter system with automatic by-pass fs 50 bp

Syphon filter system with automatic by-pass fs 50 bp

This system is composed of two syphon filters. It starts working with suction through filter 1 while filter 2 is excluded. When the sucked liquid reaches the level switch floater via the 1” 1/2 3-way vacuum interception solenoid valves, the suction is automatically commuted to filter 2. The inlet of atmospheric air in filter 1, via the 1/2” 3-way solenoid valve installed on its lid allows automatically draining the liquid through the check valve with cock located at the bottom of the filter. Once the liquid has been drained after a set time (this operation can be timed), the solenoid valve returns to its initial position, thus allowing the recreation of vacuum inside the filter, through a small flexible pipe connected to the main vacuum piping. Thanks to this solution, there is no reduction of the vacuum level at the service when the suction exchange between the two filters occurs. This exchange occurs when the liquid reaches the level switch floater in filter 2 and from that moment on, the operations described above will be repeated. The filter system is composed of:
- 2 Plexiglas syphon filters with aluminium lids and with accessories, with a capacity of 38 litres each.
- 2 1” 1/2 gas servo-controlled 3-way vacuum solenoid valves art. 07 06 11.
- 2 1/2” gas servo-controlled 3-way solenoid valves art. 07 03 11.
- 4 1” 1/2 gas 2-way manual valves for vacuum interception art. 13 07 10.
- 2 1/2” gas 2-way manual valves for the inlet of atmospheric air art. 13 03 10.
- 1 switchgear enclosed in a watertight metal casing for Volt 230/ 50 Hz single-phase electric voltage.
- 1 frame in varnished steel profiles for the assembly of all the components described above.
The syphon filtre system with automatic by-pass is recommended when there is a considerable presence of liquid in the sucked fluid and the machines cannot be stopped for draining the sucked liquid with traditional syphon filtres. Technical features:
Working pressure: from 0.5 to 2000 mbar abs.
Fluid temperature: from -5 to +50 °C
Filtering degree: 44 μ.
