069955 VUOTOTECNICA Cup holder

Along with all the other features they share with the other special cup holders, these also 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.
