Motorized ball valve could be fully closed and fully opened up by only rotating 90°.Based on the classification from the application, the electrical operated ball valve could be classified by on off function ball valve and regulating fuction ball valve. It has the benefits of simple connection,compact structure,small size,lightweight,small resistance, stable and reliable operation and so forth.

Working principle of motorized ball valve: the two inch electric ball valve is operated by DC24V, AC220V or AC380V power current, and directly receives the unified standard signal (4-20mA Electricity,-10mA Electricity or 1-5V Electricity,-10V Electricity),that is changed into the displacement akin to the input signal.The angular displacement ( to 90°) moves to alter the rotational opening from the valve ball, so a particular input signal matches a particular position opening degree, and also the proportional adjustment action is recognized.
