We were established in 1966 in Willich, North Rhine-Westphalia, as a spin-off of Carl Aug. Rothstein AG ‒ a company with over 90 years of experience fitting valves to the very first WC cisterns. Since then, we've supplied millions of brass float valves and other plastic components to the plumbing, air conditioning, agricultural, foodstuffs and chemical industries for construction and industrial engineering purposes. In addition to the 480 plastic valve, we developed and patented the first automatic poultry drinking trough and sold it worldwide. Continuous improvement and the addition of trade products in the animal drinking systems sector (marketed under the brand name JFC in Germany) under our current management has entailed extensions to the premises at our Tönisvorst location, based at the meeting point of Krefeld/Düsseldorf/Viersen/Duisburg in Germany. We cater for wholesalers and industry swiftly and with a focus on service. Our success is based on over 52 years regulating the fill level of water and other media!
