Functions and applications :

StopSilent preventer’s valves close gently and quietly and are therefore building materials installed in houses.

Water Installation in Houses

StopSilent preventer’s valves close gently and quietly and are therefore building materials installed in houses.

In the water supply, the flow direction is defined by check valves. Also for accurate water measurement, this is important for water suppliers to rely on the reliable StopSilent preventer’s valves.

Water Distribution System

In the water supply, the flow direction is defined by check valves. Also for accurate water measurement, this is important for water suppliers to rely on the reliable StopSilent preventer’s valves.

StopSilent® as a foot valve is often adapted to customer requirements in order to minimize pressure loss. The fine membrane as a sealing element provides additional operational safety.

Food Industry

Stop Silent® valves in the production lines with pasty media, Stop Silent® is characterized by its simple design. In particular compared to mechanical valves, the elastomer diaphragms do not stick and wear out. And this makes Stop Silent® reliable.

Process engineering

In the process engineering production plants, StopSilent ensures the direction of rotation and makes it possible to mix dangerous media.

Diagram in Motion

The diaphragm is unloaded in the perforated support cone and the sealing lips lie on the inner surface of the cone and make the return flow impossible.

As the pressure increases in the direction of flow, the membrane deforms and flows through the medium.

If the flow decreases, the diaphragm moves back
to its original position and closes the valve.

Die Membrane liegt in unbelastet im gelochten Stützkegel und die Dichtlippen liegen auf der Innenfläche des Kegel und verunmöglichen den Rückfluss.
