Unbalance labyrinth control valve description
uses a labyrinth cage combined with a pressure-balanced spool design. It is composed of a plurality of cylindrical discs (layers) with labyrinth mazes distributed on the same surface, Different mazes are designed based on different media processing parameters.Diameter and laminated layer array synthesis cage, the cage divides the total flow path into many small and twisted or even stepped throttle paths, forcing the fluid to continuously change the flow direction and flow area and gradually reduce the fluid pressure to achieve Prevent the occurrence of flash evaporation and cavitation and prolong the service life of the valve trim. This type of internal structure is suitable for all kinds of process fluids that are prone to generate cavitation by blocking flow
