New design – new features.
The new GEMÜ R480 Victoria series of butterfly valves scores highly thanks to their design advantages during assembly, in operation and in the event of maintenance.
Made by GEMÜ – the new GEMÜ R480 Victoria series of butterfly valves.
With the help of state-of-the-art robot technology and a sophisticated transport system, the unmachined parts for our butterfly valves are produced in-house, from the initial milling right through to the high-quality coating.
The in-house machining of our butterfly valves gives us much more control over processes that are essential to quality.

Uranium removal and partial deionization at the Trollmühle waterworks
Currently, the waterworks at the Trollmühle water supply authority in Windesheim near Bingen am Rhein supply approximately 43,000 people in 14,000 households with 2.2 million m³ drinking water per year. At peak times, this means a daily dispensing volume of up to 8500 m³. On the one hand, Krüger WABAG/VWS Deutschland GmbH implemented the URANEX® system, which is used to minimize the water's geologically caused uranium content by means of ion exchange. On the other hand, partial deionization by ion exchange is achieved using the CARIX® procedure.
DVGW drinking water tank
Along with spring tapping, wells and pumping stations, treatment and supply systems, how the water is stored has a considerable influence on the quality of drinking water. In contrast to the previously popular traditional concrete reservoirs, such as those typically found in water towers, large stainless steel tanks offer new prospects and improved quality features for municipal drinking water systems. The water tanks can be accommodated in a simple structure which is cost effective to build and can be easily adapted, both structurally and visually, to fit the on-site conditions.
Sea water desalination by reverse osmosis
Singapore began tackling their drinking water supply problem a few years ago. The first large sea water desalination plant “TUAS Desalination“ was designed and built by Hyflux Ltd. The system operates according to the reverse osmosis principle and produces more than 136,000 m³ of drinking water per day. This amount is enough to fill about 55 Olympic size swimming pools.
