NON-INTRUSIVE INTELLECTUALIZED ELECTRIC ACTUATORS
Specifications
Non-intrusive design audio-visual easy adjust
Measurement of position & torque reliable
1.GENERAL
SND-Z non-intrusive intellectualized electric actuators are designed with introduced technology from overseas and developed by cooperation. 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.
