New at Sistag

Gigerwald Dam

High-level advice

Why only show up when there are problems? Our service technicians are on the road much earlier, inspecting construction sites and advising our customers on site. Recently, for example, at the impressive Gigerwald dam wall. A Wey knife gate valve is currently blocking the bottom outlet. The outlet is to be moved many meters upwards to protect the turbine from debris.

Assembly training Sistag GmbH

Hands-on

How many people are needed to assemble a knife gate valve? Basically only one. However, many more could do it – to be precise, most of our team.

Production Ettlingen

Production site Ettlingen

The shelves are slowly filling up and the assembly of knife gate valves is progressing. Only two months after the opening, pallets of valves are leaving our new Sistag plant in Ettlingen almost every day. We are proud to see how everything is slowly picking up speed and look forward to continuing to push ahead.
