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