Our technical features of diaphragm check valves
The check valves of Lasso Technologie AG are equipped with a diaphragm to prevent the back flow of liquids and gases. When the membrane is closed, only a low noise level is generated and water hammer is avoided. The anti-reflux valve guarantees a reliable closure even with granular liquids (sandy water). In addition, our diaphragm check valves serve as raw filters and thus secure pumps and systems. We guarantee a long product life thanks to the absence of moving mechanical parts subject to wear.

Hard shell, soft core – Stop Silent is a valve cone out of stainless steel and a high quality rubber diaphragm
The harmonious interaction between the two main players of Stop Silent®
Stop Silent® check valves guarantee the controlled direction of flow and reduce the water hammer effect to a minimum.
The Stop Silent valves consist of two primary components: The valve cone made out of stainless steel and the flexible rubber diaphragm.
The valve cone, which stands out with its extraordinary design, serves as a coarse filter. This filter protects the casing pump as well as the facilities. The gently closing rubber diaphragm persuades through its safe and high sealing characteristics. The valves can bear up to a flood protection strain of 16bar (232.1psi).

Stop Silent® valves are distinguished through their light construction technique and their high capacity. In order to guarantee a frictionless service we recommend replacing the rubber diaphragm every five years.
