Vacuum valves and solenoid valves

Suction valves for vacuum press bags

Suction valves for vacuum press bags

The suction valves described on 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 has been inserted.
A silicone seal, to be placed between the two elements and the press bag, guarantees a perfect vacuum seal. Manual two-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.
Maximum temperature of use: 220 °C
Product codes: VSS3/8 VSS1/2

Plunger valves

Plunger valves

Plunger valves are composed of a natural colour or chrome-plated cylindrical brass body, depending on the items, of a steel plunger with a conical valve, a thrust spring, a nylon disc whose task is to thrust the spring onto a larger contact surface, thus avoiding unsightly prints on the load to be gripped.
Connected to vacuum, they are normally closed.
They activate suction, thus creating a vacuum, only when the plunger is in contact with the gripping surface.
They are also available in various versions, all suitable for our vacuum cups.

Shut-off valves

Shut-off valves

These are special one-way valves that, when properly calibrated, allow a certain quantity of fluid to go through; afterwards, if the fluid continues to go through, they automatically close.
These shut-off valves have been specially designed to be applied on the cups and, in case of lack of objects to be gripped, of defective grips or leaks, they automatically deactivate suction, thus preventing any reduction of the level of vacuum on the other gripping cups.
They are provided calibrated and commissioned, ready to be installed. They are made with anodised aluminium and can be supplied in different shapes and sizes upon request and for a minimum quantity to be defined in the order.

Check valves

Check valves

These one-way valves are made with bronze and brass with a seal in NBR nitrile rubber or, upon request, in Viton®, only for series 10 ... 11.
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.

Membrane check valves

Membrane check valves

These valves have the same features of the previously described check valves, but they are made with anodised aluminium, which makes them particularly light. The seal is guaranteed by an EPDM membrane instead of the metal shutter with NBR seal.
Thanks to these features and their modern design, they are recommended for pneumatic vacuum generators and, of course, on vacuum pumps.

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 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

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.
Technical features
Operating pressure: from 0.5 to 850 absolute mbar
Temperature of suctioned fluid: from -5 to +60°C

Electric coils

Electric coils

Electric coils are windings of copper wire on nylon coils fully plasticised in synthetic resin which activate the electromagnetic actuators with which the solenoid valves are provided. Crossed by an electric current, these coils generate a magnetic field which activates the mobile core inside the actuators; the mobile core features a built-in or fixed shutter which cause the valve commutation by opening and closing their mouths.
The standard electric coils are 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 with connector inserted.
Tolerance permitted on the nominal voltage value: ±10%.
Tolerance permitted on the frequency value: ±5%
Room temperature: from -10 to +45°C
Fluid temperature: from -10 to +95°C
Electric absorption: 8 - 20 V.A. with AC and 6.5 - 18 W with DC.
The electric coils can be rotated 360°

Connectors for coils

Connectors for coils

Connectors are fundamental for bringing electric current to the solenoid valve coils.
They are available in the simple plug version installed as standard and, upon request, with LEDs to signal the presence of voltage, with anti-interference circuits, protection devices against overvoltage and polarity reversal.
When correctly installed, all connectors provide full protection against water jets, according to EN 60529 standards (protection class IP 65).
Moreover, they meet VDE 0110-1 /89 standards, working voltage up to 250 V, overvoltage category II, Degree of use 3, regarding insulation class.
In all contacts, a snap joint between contact holders and the external protection guarantees a safe locking and easy assembly.
Safe locking is essential for guaranteeing the operator full protection when handling the connector.
The contact holder can be easily extracted from its casing simply using a screwdriver.
This operation also allows orienting the earthing contact in the desired direction.

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.

Multi-function modules with built-in vacuum solenoid valves

Multi-function modules with built-in vacuum solenoid valves

The needs of technical designers in the packaging sector and in the automation sector in general to have more vacuum combined with different functions in the smallest possible space has led us to design and implement this new series of multi-function modules.
Each module has two internal solenoid valves built inside it. Their ducts house the seats for the flow control valves, which can be operated externally by means of special knobs. Various connections made at different points allow for connection of the module to instruments for reading and checking the level of vacuum, such as vacuum gauges, vacuum switches, transducers, etc.
There are three modules currently available:
- Module A: the basic module with two integrated 1”1/2 and 1” solenoid valves, two flow regulators and several additional connections.
- Module B: with two integrated 1/2 "and 1" solenoid valves and two flow regulators. Can be combined with modules A and C.
- Module C: module with two integrated 1/2” solenoid valves, a flow regulator and an additional connection.
Can be combined with module A or B.
The combination of modules A, B and C, feasible using special stainless steel tie-rods, allows for the application of various functions from a single source of vacuum, as well as allowing for the elimination of numerous pipes and fittings, often causing leaks. The multi-function modules are supplied already tested to a guaranteed final level of vacuum of 0.5 mbar and perfectly sealed.
The technical characteristics are those of the pneumatically actuated three-way vacuum solenoid valves:
- Servo-control pressure: 6-7 bar; 4-6 bar for version LP, with non-lubricated compressed air, 5 micron filtration, according to standard ISO 8573-1 class 4
- Operating pressure: from 0.5 to 3000 absolute mbar
- Electric coils: 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
- Protection degree IP 54; IP 65 with connector inserted.
- Tolerance permitted on the nominal voltage value: ± 10%
- Electrical power of the coils: from 1 to 2 W, depending on the electrical voltage
- Temperature of suctioned fluid: from – 5 to + 60°C
The ideal use of these multi-function modules is on vacuum thermoformers and vacuum thermo-welders, but they are also widely used on packaging and filling machines in the packaging sector and in all those cases where it is necessary to manage the vacuum at different points and times. Upon request, the modules can be customised and implemented with solenoid valves up to 3” gas. Contact our technical department for further information.

Solenoid pilot valves with interface valves and micro connectors EN 175301 - 803 (EX DIN 43650) - C, for solenoid pilot valve electric coils

Solenoid pilot valves with interface valves and micro connectors EN 175301 - 803 (EX DIN 43650) - C, for solenoid pilot valve electric coils

Connectors are essential elements for bringing electricity to solenoid pilot valves with built-in low absorption coil.
They are available in the plug version, with a LED for signalling the presence of voltage and, upon request, with anti-interference circuits, with protection against overvoltage and polarity inversion.
All connectors provide full protection against water jets, according to EN 60529 (protection class IP 65), when correctly installed.
They also meet VDE 0110-1 /89 standard, working voltage up to 250 V, overvoltage category II, degree of use 3 regarding insulation class.
In all contacts, a snap joint between contact holders and the external protection guarantees a safe locking and easy assembly.
A safe locking is essential for guaranteeing the operator full protection when handling the connector.
The contact holder can be easily extracted from its casing simply using a screwdriver.
This operation also allows orienting the earthing contact in the desired direction
