The electric low-noise regulating valve adopts a multi-stage pressure reducing sleeve and anti cavitation valve internal design, which gradually consumes fluid energy through a labyrinth flow channel or a staged opening structure; Equipped with high-precision intelligent electric actuators, it directly drives the valve core to achieve micrometer level control without the need for a gas source; The valve body adopts streamlined flow channels and hard sealing materials, effectively suppressing turbulence and cavitation effects.
