Introduction:
ISCV stepping motor control valve is one of widely used in idel speed control equipment in the world, it is applied in auto fuel injection system to control volume of air supply, it make motor speed reach a demand objection.

Principles of operation
It is incorporated a permanent magnetic rotor, magnetically conductive stator, and thread shaft which turn rotary motion into line motion. it use step signal supplied by system to control switch, so that the rotor run in clockwise or anticlockwise, this motion make the thread shaft pull in or pull out, accordingly the cross section of the air passage is adjusted, futher it stabilize the idel speed and reach a ideal speed.
