Mini vacuum cup holders with plunger valve
They share the same mechanical features at the other mini vacuum cup holders.
Their distinctive feature is the plunger valve solidly connected to a conical spear valve, which activates suction, and therefore creates vacuum, only when the cup comes into contact with the load to be lifted.

Mini vacuum cup holders with plunger valve and built-in bush
The technical and mechanical features are the same as for the mini vacuum cup holders with plunger valve described on the previous pages. Their distinctive feature is their threaded hexagonal bush, which allows them to be directly assembled to the vacuum manifold, thus saving time and eliminating pipes and fittings.

Mini vacuum cup holders with plunger valve with no springing
They have the same function as the mini vacuum cup holders with plunger valve but, for further bulk reduction, the cushioning spring, the threaded pipe with nuts for fixing to the automation and the quick coupler have been removed.
This type of cup holder is to be directly assembled to the vacuum manifold. To allow quick assembly, its end is provided with a threaded male shank.

Basic vacuum cup holders with plunger valve
They offer the same mechanical performance at the basic mini vacuum cup holders. They are characterised by a plunger valve solidly connected to a conical spear valve, which activates suction, and therefore creates vacuum, only when the cup comes into contact with the load to be lifted.
The actual springing stroke is:
- For height C= 28 mm 16 mm
- For height C= 65 mm 49 mm
- For height C= 95 mm 74 mm

Basic vacuum cup holders with plunger valve, with no springing
Their function is the same as the previously described basic vacuum cup holders with plunger valve but, for further bulk reduction, the cushioning spring, the threaded bush with nuts for fixing to the automation and the quick coupler have been removed. This type of cup holder must be assembled onto the vacuum manifold by means of a threaded male shank on its end.

Special vacuum cup holders with plunger valve
They share the same mechanical features at the special vacuum cup holders. The addition of a plunger valve solidly connected to a conical spear valve, which activates suction, and therefore creates vacuum, only when the cup comes into contact with the load to be lifted.
With these cup holders, it is no longer necessary to install cocks on the suction hoses; for this reason, they are recommended in all those cases in which there is a chance that not all the cups come into contact with the load to be lifted (because of an uneven or incomplete load).
The actual springing stroke is:
- For height C= 55 mm 37 mm
- For height C= 110 mm 84 mm

Plunger valves
Plunger valves are composed of a cylindrical brass body, a steel plunger with a conical valve and a thrust spring.
Connected to vacuum, they are normally closed.
They activate suction, thus creating vacuum, only when the plunger is in contact with the gripping surface.
They are available in various versions, all suitable for our vacuum cups.

Mechanically operated valves
These valves are composed of an anodised aluminium body, a steel pin solidly connected to a conical shutter and of a thrust spring.
Connected to vacuum, they are normally closed.
They activate suction, thus creating vacuum, only when the pin is activated by the cams or any other mechanical device.
They can be used as an alternative to plunger valves when these cannot be assembled onto the vacuum cups.
