Customer opinion



Wasserverband Eifel-Rur

Within the scope of the hydraulic steel construction works performed at bottom outlet 1 of the Olef Dam, a new tapered seal was required for the dismantling joint (DN 2000) from the year 1957 welded to the upstream side wall pipe. As the dimensions of the tapered sealing profile could neither be found in our own available documentation nor be obtained from the manufacturer and as a longer-term downtime of bottom outlet pipe 1 and an order after the dismantling of the old seal were out of the question, VAG was asked for assistance in this matter.
Thanks to the short-term, competent and speedy assistance provided by you and your employees it was possible to receive a suitable replacement seal from your company within a very short time. During the subsequent commissioning of the bottom outlet, there were no complaints; the dismantling joint with the new seal was absolutely tight.
We have already noticed the VAG in other construction projects as a real solution provider and we would like to take this opportunity to thank you once again for your great help.

As a company in the power generation sector we need to be able to count on reliable suppliers for each division. Some time ago, we had a big challenge to overcome - to be specific, we had to upgrade some equipment of our hydropower plant. To contact VAG was the right choice. The engineers of VAG developed possibilities which would fit into our plant and realize our ideas in an ideal way. They participated and supported us by choosing the right valves and more importantly, they delivered valves with reliable functions and tightness. Also the VAG EKN® type butterfly valves in bigger sizes have been running smoothly since their first operation.
We are really impressed that VAG is a solution provider for all stages in a project: from the planning to the realization to the postproduction and their technical service. VAG was on site when we needed them. Ever since then, we have had fundamental trust in VAG ranging from the quality of their products to their customer service; everything is as it should be.
