Angle Type Unbalanced Labyrinth Control Valve

Unbalanced Labyrinth control valve adopts the labyrinth cage and unbalanced trim design. The labyrinth sleeve is composed of cylindrical discs with many coaxially distributed labyrinths. According to different technological parameters of the media, different labyrinth specifications and piling layers are designed to form the cage and the cage divides the whole flow channel into several tiny circuitous or step flow channels, forcing the fluids to continuously change the flow direction and flowing area and gradually reducing the pressure of fluids, so as to prevent the occurrence of flash evaporation and cavitation and prolong the service life of the trim. The unbalanced single-seat is adopted. The trim is suitable for service conditions under which blocked flow will easily be produced and cavitation will be caused. The unbalanced trim is suitable for applications of small sizes and high temperature.
