The 700 series hydraulic valve data is used in drinking water applications in buildings. The range is extremely comrehensive with Sigma-EN , Sigma-ES and “Classic” models available in Flanged, threaded and rolled groove. Configerations also in Y patern and angle pattern in many of the ranges.
Materials available in Ductile Iron and Stainless Steel for different water conditions in buildings.
The imploding vapor bubbles in the cavitation phenomena create a sonic wave in the fluid that upon impact with the pipe wall create vibrations that can result in disturbing noise levels.
Many factors affect the noise level generated by pipe fixtures, such as pipe material and wall thickness, installation rigidness, acoustic conditions in the installation space, fluid physical and chemical characteristics and many more.
In terms of hydraulic conditions, working at values greater than 0.5 with control valve can significantly reduce noise.
