PRESS RELEASE
Mannheim, September 2010
VAG EKN® Butterfly Valve in large nominal diameters
A highlight that just cannot be missed at the IFAT in Munich is VAG’s DN 4000
butterfly valve. With its striking internal diameter of 4 metres, a height of 4.80
metres, a width of 6.90 metres, a depth of 1.75 metres and a weight of 47
tonnes, the VAG EKN® Butterfly Valve is the largest valve exhibited at the
trade fair.
Even with the largest nominal diameters, the customer can rely on the
consistent premium quality supplied by VAG. The top-quality corrosion
protection, ensured by a 250 µm epoxy coating according to the GSK
Guidelines, makes the valve permanently resistant to corrosion.
The VAG EKN® Butterfly Valve, tried and tested over many years, is available
in all standard nominal diameters ranging from DN 100 to DN 4000.
Depending on its nominal diameter, it can be used for working pressures of
over 50 bars. The double-offset bearing of the disk whose centre of rotation is
outside the sealing level both horizontally and vertically protects the profiled
seal against deformation and abrasion.
The absolute tightness in both flow direction guarantees high operational
safety. The double O-ring seal of the shaft bearings, the closed bearing lugs in
the axle bearing area as well as a body sealing seat made of nickel weld
deposit ensure long-term reliable operation. The VAG-Group can furnish
numerous references for this reliability which prove the trouble-free function of
the VAG EKN® Butterfly Valve even over decades.
The main field of application of the VAG EKN® Butterfly Valve is the local
water supply system. From the extraction of water to transport pipelines and
water treatment plants up to drinking water supply networks. For decades, the
VAG EKN® Butterfly Valve has proven its reliable function also in main cooling
water lines of power plants and hydropower stations in many projects worldwide.
For more than 130 years, VAG-Armaturen GmbH, the modern company with a
long tradition, has been operating wherever water is treated, stored and
distributed. With more than 1000 employees world-wide, the valve
manufacturer is a global player and as a provider of systems and solutions
