How does the hygienic valve work and what are the advantages over conventional valves?

The hygienic valve consists of a valve body and a bayonet quick-release nut. For daily cleaning, the quick-release nut can be opened with a flick of the wrist. This makes the suction cup freely accessible and can be cleaned separately. The valve has a non-return valve on the inside, which allows the valve flow to be thoroughly cleaned with a round brush. The valve and the bayonet can dry out with the suction cup on the drying aid.
