The bite ball valves have been compared to conventional valves. The study is made by the George Morris centre in Canada. A summery of this test is downloadable below. The newsletter is a short summery of the study and the reading is very interesting. There has been editorial text about this in several large magazines like USA’s No. one pig magazine: National Hog Farmer and Germany’s largest agricultural magazine: Top Agrar.
The George Morris centre concludes that the bite ball valves are saving substantial amounts of water by cutting down on the water spillage. Their test barn had 35% lower total water consumption and still maintained the same production results. Their end conclusion is this: “Overall, the strength of this technology lies in the fact that it is simple, environmentally friendly, and profitable”. A summary of the report can be downloaded here.
