Valve Multi Turn Motor Valve Intelligent 90 Degree Motorized Electronic Actuator

The product is a new generation of built-in DSP(DSPIC digital signals, simple called DSC) of the United states Microchip Technology Inc. at the core. It adopts frequency control technique with contemporary advanced to realize ideal mild start and orientation control. And it has reduced machine impact. I t has a series of self-diagnose and self-protect function for over torque and over heat. It has excellent protect effect to terminal adjusted unit of value. It adopts conversion-frequency control, which can flexible adjustment for output thrust (torque) during orientation process to realize
high-precision orientation and without over rush. Its start-current approach motor's rating current, which is start-current of routine switch control for one-eight to one-fourth and reduce strike for this produce's driving part and motor.

The actuator is by the composition of the conversion-frequency motor, position sensor, worm wheel, worm, driving shaft, control unit, local operation panel, hand-wheel. The control unit accepts 4~20mA or discrete control signal and driving motor's turning. The motor drives worm which driving worm wheel again to drive output shaft turning. The position sensor checks position of motor's turning and transmit position of value to control board. When the control board checks that the position signal and given control signal is the same as position appointed, cutting motor's power, the self-lock
character of the worm and worm wheel make the actuator stop running.
