INLINE SLEEVE VALVES 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. High risk damage zone...

INLINE SLEEVE VALVES Tipycal Valve Section The indicated flow is the one we suggest for the regulation of a standard valve. Upon request it is possible to manufacture holes cylinders in according to the requested flow rate and dissipation capacity in base to specific performance diagrams.

INLINE SLEEVE VALVES K (head loss coefficient) - opening (%) 1.000.000 The Flow rate diagram depends on the type of the required use for the valve. In case of a regulating valve use, the diagram will have a lower value variation of flow against the opening degree in the range of operating work, in order to have a more linear variation of flow rate with a minimum head loss. In case the valve use is firstly for dissipation use, the diameter of holes of the cylinder will be made smaller with variable pitch and so with more head loss than the other config
