Vacuum valves and solenoid valves

Suction valves for vacuum press bags

Suction valves for vacuum press bags

The suction valves described in this page have been designed for a quick vacuum connection on press bags for composite fibre products.
These valves are composed of a steel distributor, to be inserted inside the bag, equipped with a cam housing suitable for the quick coupler for the vacuum connection. The latter is made with reeded and anodised aluminium and is easily coupled with the distributor by simply rotating it on its axis by 90°, once it’s been inserted.
A silicon seal to be placed between the two elements and the press bag, guarantees a perfect vacuum seal.
Manual 2-way valves, quick couplers or simply flexible pipe fittings can be assembled onto these valves.
They are currently available in the two versions indicated in the table, but can be provided in different sizes and shapes upon request for a minimum amount.

Check valves

Check valves

These unidirectional valves are made with bronze and brass with a seal in NBR nitrile rubber or, upon request, in Viton®.
To ensure a practical assembly they are available in two versions: horizontal and vertical.
Fitted on the vacuum pump suction inlet, as soon as the latter stop, these valves prevent the air from returning in the plant (piping, tanks, autoclaves, vacuum gripping systems, vacuum cups, etc.), guaranteeing a perfect seal and preventing the oil from returning into the pump stator, which would cause considerable damages.
Therefore, check valves are mandatory on all vacuum pumps with lubrication that do not have them built-in.

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.

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.

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

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.
The electric coil of the solenoid pilot valve is fully 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 DIN 43650) -C. 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.
Technical features
Working pressure: from 0.5 to 850 mbar abs.
Temperature of the sucked fluid: from -5 to +60 °C
