DF/SND Series Intellectualized Multi-turn Electric Actuator

CHANGZHOU-SCHNEIDER (abr. as SND) non-intrusive intellectualized electric modulating actuators are products of new generation developed by cooperation on the basis of introducing the newest control technology from Schneider.These mechanic-electronic products have been integrated advanced multi-control technologies such as absolute coding technology, sensor technology, bus-mastering technology, infrared remote control technology, LED, magnetic control switch and advanced manufacturing technology.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.
