DRINKING VALVE

摘要

Drinking valves (10) having a plastics housing (18) are susceptible to aggressive cleaning agents. The invention makes provision somewhat to increase the wall thickness of the plastics housing (18) by the wall thickness corresponding to at least 17% of the maximum inside diameter of the plastics housing (18). It has surprisingly been shown that a plastics housing (18) having such a wall thickness is more capable of resisting aggressive cleaning agents than conventional drinking valves having a plastics housing.
