Controlling air pressure at the wastewater treatment plant in Hangzhou, China
VAG RIKO Plunger Valves are as reliable in air pressure systems as they are in water supply systems
Situated on the east coast of China, the city of Hangzhou harmoniously combines ancient tradition with modern technology. With a history going back 4,700 years, Hangzhou is the cradle of Chinese civilization. In the 13th century, Marco Polo spoke of 'one of the finest and most beautiful cities in the world'. Traditional silk making huts and plantations of exquisite green tea characterize the landscape.

New safety standards for nuclear power station Unterweser
High quality, custom-made VAG valves regulate the supply of cooling water
When the nuclear power station Unterweser was connected to the grid in 1978, it was the largest in the world. Some 10,000 billion KWh of electricity is generated here every year by a pressurized water reactor. The nuclear reactor, also known as Esenshamm or Kleinensiel, takes up a prominent place among the 17 German nuclear reactors.

Refurbishment and renewal of all pipelines in the city of Rötz, Germany
VAG provides all valves and numerous VAG BAIO®plus system fittings
Water is not automatically drinking water as the 3,500 citizens of the city of Rötz found out from experience: impurities and leaks repeatedly caused problems. Moreover, the supply of extinguishing water and of backup water needed improving.
In 2004, Mayor Ludwig Reger and the aldermen decided to overhaul the entire supply system. An investment of 6 million euros was secured and allocated to the project with the help of the Free State of Bavaria.

Rapid supply of drinking water for Ankara, Turkey
Immediate relief for severe water shortage in the Turkish capital
Ankara, the capital of Turkey since 1923 and the country's second largest city, is located in one of Turkey's driest areas. The rapid rise in the number of the city's inhabitants to more than four million and the nationwide drought led to a severe water shortage in 2007. The city actually had to implement a restriction policy.
The mayor of Ankara, Melih Gökcek, spontaneously gave the go-ahead for a gigantic pipeline project that promised to quickly bring permanent relief.

Flood protection for the City of Bogen
VAG designs special valves to protect the City of Bogen against floods.
The 'Gate to the Bavarian Forest' is how the Lower Bavarian City of Bogen describes itself. The medieval city is situated on the banks of the Danube between Straubing and Vilshofen. With the growing risk of floods, the proximity to the river is becoming an increasing danger to the 10,000 inhabitants and their possessions. That is why RMD Wasserstraßen GmbH and the water board of Deggendorf developed a flood protection plan for the City of Bogen as part of the in-depth investigations into the regulation of the section of the Danube between Straubing and Vilshofen. The plan is to prevent flood water from the hinterlands reaching the city by storing it in retention basins and using pumps to channel it through the Bogen stream into the Danube.

Fire water supply at Frankfurt Airport, Germany
The complete fire-fighting system of Frankfurt Airport is to be modernised within the next few years using the most powerful standpost hydrants made by VAG. The future-orientated technology of the hydrants will also serve in the supply of such important new buildings as Terminal 3 right from the start. The VAG NOVA Standpost Hydrant in dimension DN 150, which is unique in the market and has been designed especially for the protection of modern and sensitive industrial plants and infrastructure systems, will be found in all places where maximum safety and top performance are an issue. Over 26 hydrants are already in service on the site of Germany's largest factory building - the Airbus 380 hangar.

Water treatment plant in Brezno, Czech Republic
VAG-Armaturen ensures remediated mine water is returned to the environment.
The mining industry has a long tradition in the Czech Republic. Archaeological finds prove the search for precious metals started as early as the 13th century. Today, VAG ensures that mining has a minimal effect on the environment. Outdated technologies have been replaced with VAG valves, which guarantee that the applicable limit values are not exceeded after the mine water has been remediated. Every year, 2.5 million cubic metres of the highest quality water are remediated, making it safe for the environment and for human consumption. With its integral approach to quality and excellent service, Jihomoravská Armaturka, a manufacturing and sales company within the VAG group, came out ahead of the clearly cheaper competition.

VAG Hydrants 100 Years of Service
In Koszalin, water is referred to as the city’s biggest treasure. And so it is not surprising that handling this precious resource has had a long tradition in the Polish city.
As early as in the 18th century, people began to develop and install a professional water supply system in the city then called Köslin and belonging to Prussia. At the end of the 19th century, the wooden water pipelines were replaced by pipes made of cast iron, and this as the birth of the city’s first modern water supply system.
The renovation of household water supply systems all over Poland, which was completed by the beginning of the 20th century, was partly effected using VAG valves (formerly called Bopp & Reuther). Gate valves, standpost and underground hydrants, house connections, even entire water supply systems were exported from Mannheim, Germany to Poland and to other countries.
This is also true for the hydrants installed in Koszalin. Until 2004, i.e. for over a century, they worked completely trouble-free. Now the old-age pensioners made of cast iron are exhibited in the Muzeum Wody as witnesses of the history of Koszalin and its water.

The Tecklenburg biogas plant
The exploration of renewable energies points the way to the environmentally sound generation of power in the 21st century. Biogas plants using renewable raw materials as green resources are a key technology in this respect. They are climate neutral, make use of agricultural products among others and thus have a perfect ecobalance. VAG valves help to accurately control the plants’ complex industrial process equipment and to make them even more efficient through automation. One example can be found in Tecklenburg at the foot of the Teutoburg Forest in Germany. Since January 2007, the Tecklenburg biogas plant has been operating there, using pneumatically actuated valves made in Mannheim, Germany.

Unique dam project in Algeria
Algeria is situated between the Atlas Mountains in the north and the Sahara desert in the south. Most of the country’s water is supplied from dams. The dams are run by the government, while the pipelines and purification plants are run by the municipalities. The amount of water supplied from the reservoirs did not always match the amount received by the municipalities. This metering and documentation problem was solved by VAG valves: a 2 million Euro project that is yet to be equalled in type, size and cost.

Drinking water reservoir Kleine Kinzig, Germany
VAG valves and FESTO pneumatic actuators in the new treatment stage
The Kleine Kinzig water supply is the only drinking water reservoir in the state of Baden-Württemberg, and is one of the state's central water supplies. The reservoir is located in the vast forest between Freudenstadt and Alpirsbach and is fed by creeks and sources in the Black Forest. With a maximum holding capacity of 13 million m3, it supplies 250,000 inhabitants. VAG valves were used to build a preliminary purification stage.
