Special vacuum cup holders with plunger valve
They share the same mechanical features as basic 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.
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).
They are composed of:
- A nickel-plated steel stem for fastening the vacuum cup;
- A threaded brass bush, equipped with two anti-friction bushings, fitted with two ring nuts for fastening the vacuum cup holder to the automation;
- A spring to cushion the impact of the cup with the load to be lifted;
- A safety washer;
- A quick coupling for connection with the suction hose;
- A solidly connected plunger valve with a conical shutte.

Special vacuum cup holders with push valve
They share the same technical and mechanical features at the special vacuum cup holders. Their distinctive feature is the push valve on the cup support, which activates suction, and therefore creates vacuum, only when the cup is in 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 same push valve can also be applied with no modification to the special articulated cup holders. They are composed of:
- A nickel-plated steel stem for fastening the vacuum cup;
- A threaded brass bush, equipped with two anti-friction bushings, fitted with two ring nuts for fastening the vacuum cup holder to the automation;
- A spring to cushion the impact of the cup with the load to be lifted;
- A safety washer;
- A quick coupling for connection with the suction hose;
- A plunger valve.

Special vacuum cup holders with built-in shut-off valve
Along with all the other features they share with the other special vacuum cup holders, , these have a built-in shut-off valve. The purpose of the shut-off valve is to automatically close suction when the cup is not in contact with the surface of the load to be handled or in case of a faulty grip or of considerable transpiration.
This thus prevents the reduction of the level of vacuum on the remaining cups of the system which are regularly handling the load. The clear advantage of this system is that the positioning or the exclusion of the non-gripping cups are no longer binding.
Cups with diameters between 85 mm and 150 mm can be assembled onto these cup holders, as long as they are provided with a threaded 3/8” gas female support.
They are composed of:
- A nickel-plated steel stem for fastening the vacuum cup;
- A threaded brass bush, equipped with two anti-friction bushings, fitted with two ring nuts for fastening the vacuum cup holder to the automation;
- A spring to cushion the impact of the cup with the load to be lifted;
- A safety washer;
- A quick coupling for connection with the suction hose;
- A shut-off valve.

Special articulated vacuum cup holders
The distinctive feature of these cup holders is their articulated joint in hardened steel, which allows the flat cups installed on these cup holders to adapt themselves to the loads to be lifted even if not completely parallel with the cup plane, as well as to compensate possible verticality errors that can arise between the cup holder and the automation fixing support. Their technical and mechanical features are the same as the other previously described special vacuum cup holders.
They are composed of:
- A nickel-plated steel stem for fastening the vacuum cup;
- A threaded brass bush, equipped with two anti-friction bushings, fitted with two ring nuts for fastening the vacuum cup holder to the automation;
- A spring to cushion the impact of the cup with the load to be lifted;
- A safety washer;
- A quick coupling for connection with the suction hose;
- An articulated joint in galvanised steel.

Special stainless steel anti-rotation vacuum cup holders
Designed for the robot-automotive sector, these cup holders offer ideal solutions to various handling problems that arise in all industrial sectors.
In addition the characteristics of the previously described special vacuum cup holders, their distinctive features are their brass stem with hexagonal cross- section and the steel drive bush, also with hexagonal hole. This structure prevents the stem and, as a result, the cup assembled onto it from rotating on its axis.
The drive bush is equipped with two fine thread ring nuts to guarantee an accurate fastening of the cup holder to the automation. Moreover, the two ends of the stem, also in stainless steel, are threaded male or female and interchangeable. The straight quick coupler for the connection to the suction hose is screwed to one end, while the cup with support is assembled onto the other end.
They are suited for cups with a diameter between 40 mm and 200 mm, although they are especially useful for the assembly of rectangular or elliptical vacuum cups.
They are composed of:
- A stainless steel stem with hexagonal cross-section;
- A threaded brass bush with an internal hexagonal cross-section, fitted with two ring nuts for fastening the vacuum cup holder to the automation;
- A spring to cushion the impact of the cup and to, at the same time, maintain constant pressure with the load to be lifted;
- A quick coupling for connection with the suction hose.

Special vacuum cup holders with double springing
All the special vacuum cup holders previously described can also be provided in the double springing version. In this configuration, the cup holder fixing bush is located between two springs: the lower one cushions the impact of the cup with the load to be lifted during the approach phase, while the upper one absorbs the impact of the bush with the cup holder end and ensures gradual loading of the vacuum cup during the lifting phase. The use of this solution is especially recommended when the load to be handled is very heavy, rough or not perfectly flat.
They are composed of:
- A nickel-plated steel stem for fastening the vacuum cup;
- A threaded brass bush, equipped with two anti-friction bushings, fitted with two ring nuts for fastening the vacuum cup holder to the automation;
- Two springs designed to reduce and distribute impact: one serves to cushion the impact of the vacuum cup with the load to be lifted, the other to cushion the impact of the bush against the end of the vacuum cup holder;
- A safety washer;
- A quick coupling for connection with the suction hose.
