Bottle Suction Cups with Sensing Valve, VSBO, VSBO+
Presentation
COVAL has designed a complete range of 4.5 bellow suction cups, featuring a sensing valve, internal reinforcements, a 40 x 95 mm gripping lip to handle 75 cl bottles, as well as the ability to limit vacuum leakage from the network should a bottle be missing.

VSBO and VSBO+ suction cup technology features two different mechanical sensing valves that isolate the suction cups should a bottle be missing.
To increase the lifting force while maintaining a long travel distance and great flexibility for packing/unpacking applications, VSBO and VSBO+ suction cups feature an upper insert, three reinforcements inside the bellows, and a lower reinforcement or a trigger plate.

Sensing Valve Technologies
CH2 mechanical sensing valve
The CH2 sensing valve opens as pressure is exerted on the suction cup by an internal reinforcement, called a “trigger plate”. The CH2 sensing valve is only compatible with stainless steel reinforcement plates (version D6P).

CH4 mechanical sensing valve
The CH4 sensing valve opens as soon as pressure is exerted on the suction cup by a lower reinforcement called “trigger plate”. The CH4 sensing valve is compatible with stainless steel reinforcement wire or plates (versions D5P and D6P).
Insert and Reinforcements
Version D5P
3 reinforcements: stainlesssteel wire 1 lower reinforcement: polypropylene

Version D6P
3 reinforcements: stainless steel plate 1 lower reinforcement: polypropylene
Mounting Hole Distance
VSBO and VSBO+ suction cups offer a choice of two mounting hole distances: 30 or 45 mm.
VSBO+ suction cups include integrated seals for easier mounting.
