When laying a new part of the water pipeline in Utrecht, Vitens wanted to install a Hawle DN400 and two Hawle DN600 E2 gate valves. Vitens had chosen these shut-off valves due to their ease of operation and the strong quality of the materials.
Unfortunately, the area available turned out to be too shallow for the normal vertical installation of the DN600 shut-off valves. If they had been installed as normal, the shut-off valves would have protruded above the surface. For sometimes, the shut-off valves are too high for the space available because the water pipeline is not buried deep enough.
SEEING IS KNOWING
The solution to this problem situation was devised a couple of years ago by Bert: a simple yet revolutionary solution which involved tilting the shut-off valve and installing it horizontally. At the time, the solution was formulated and technically implemented through collaboration with Hawle.
The operating system of the shut-off valve had to be mounted differently. The shut-off valve was fitted with an Auma right-angle worm gearbox on which the installation kit was placed.
