The pipeline multijet valve VH4 Type it is used to dissipate the cinetic Energy of the water inside the pipeline, avoiding ≤the common negative phenomena present on it as: Cavitation, vibration and noises. Ponted the most negative and important phenomenon is the cavitation one that causes high stress and damages on the pipeline. In fact the cavitation produces gas bubbles that quickly implode. In case that these bubbles formed near metallic parts it would produce damages, erosion and vibration on the those as shown in the schematic figure beside.
