Multi-stage pressure-reducing electric control valves utilize multi-stage cage-type sleeve plugs or axial flow labyrinth plugs. Through multi-stage pressure reduction, they fully control the flow velocity of media passing through the valve, significantly reducing noise generated by high-pressure gas or steam within the valve body. Stable multi-level pressure reduction effectively prevents cavitation in liquids, making these valves reliable control devices for high-pressure applications. Actuators can be selected from domestic or imported electric actuators.
