Stop Silent - Some fields of application

Since 1976, the City of Zurich Water Department has been using Lasso Technik’s Stop Silent check valves to efficiently manage the city’s water supply. The engineer in charge of distribution, Mr. Arnold Egli, has confidence in this valve. In the event of a pipe failure, Mr. Egli knows that the pipe system will not be damaged.

In the former Ciba group, the chief engineer of the equipment department uses the Stop Silent valve for the most diverse applications in chemical equipment and in the field of energy (hot and cold).

Thanks to our stainless steel cone with a special Halar coating and Hastelloy screws, it was possible to find a very cheap solution. This cone is successfully used in chemical industrial waters.

The engineer Mr. Hollinger is in charge of the production of pralines.

In the past, production was often interrupted because the mechanical valves used blocked under the sticky mass. The costs of maintenance and cleaning became significant. A solution had to be found to remedy these frequent and costly interruptions.

With the Stop Silent check valve, production could be carried out continuously.
