CHANGZHOU-CDF non-intrusive intellectualized electric actuators are designed to control and drive electric valve.

SND Range products are units to control the operation of final control element (e.g. valves) in open control system. Among the rest, And SND actuators of Range DQ are used for the control of ball valve, butterfly valve, and damper etc.
