For us, service is a question of attitude.
As a manufacturer, we know our products like no other. That's why we are also there for you after the sale. For your questions, for maintenance and repairs or for training your team. We will never be 100% satisfied, unless you are too.
Installation
Correct installation is essential for a valve to function properly. This is especially true for our custom-made water control gates. Our experienced technicians are on the road throughout Switzerland and take care of the installation on your system.
In western Switzerland, we work with our service partner EMGA J. Donnet & Fils for installations and repairs; in Ticino we work with our service partner Premel SA. This allows us to be on site even faster.
Maintenance
We focus on sustainable solutions. Many of our valves have been in use for our customers for decades. With professional, regular maintenance, we give your valves an extra lifetime.
