The shutter slides in a pressure compensated and suitably profiled chamber to avoid vibrations and anomalous hydrodynamic loads. The closure takes place in the direction of the flow so that as the speed of the fluid (ie the pressure difference) increases, it tends to further stabilize the system. The internal profile of the valve is designed in such a way as to minimize the possibility of the occurrence of the cavitation phenomenon. The water flow is guided in a passage having a circular crown-shaped section progressively decreasing from the inlet section towards the sealing seat. The hydrodynamic profiling of the passage is optimized throughout the wall where the speed of the water is gradually accelerated and allows to keep the pressure drops low. For these reasons, the spindle valve allows you to continuously modulate the hydraulic parameters and a continuous and linear adjustment of the flow rates for the entire range of the degree of opening. DN 100-1400 range Operating pressures up to 40 bar Possibility of installing a stainless steel anti-cavitation basket to allow to dissipate high hydrostatic loads and prevent cavitation The spindle adjustment valve to adapt to the multiple uses and the different needs of the systems on which it is used, has a varied number of operating devices that can be applied for its movement: Flyer Electric actuator Hydraulic actuator Pneumatic actuator Cap and operating key Steel extension connected to a column for manual operation Steel extension connected to a column for maneuvering by means of an electric actuator mounted on it Images Close Associated documents 1118-fused.pdf (540.83 KB) OUR PRODUCTS AND TOOLS E-catalog PAM Tools INFORMATION PAMLINE TV Documentation WFP COMMITMENTS Sustainable Development Innovation ACTUALITY News SAINT-GOBAIN PAM History Lavis plant COOKIES LEGAL NOTICES SITE MAP PRIVACY DISCLAIMER EXPLANATORY NOTE DL231 WE USE COOKIES ON THIS SITE TO ENHANCE YOUR USER EXPERIENCE By clicking the Accept button, you agree to us doing so.
