Features
The electric butterfly valve has a small operating torque and is the smallest operating torque among all valves. It is the execution unit of the instrument in the automatic control system. It is powered by AC220V, AC380V or DC24V power supply voltage, and accepts from (DCS, PLC) systems or adjustment instruments. , the operator and other input (4-20mA, 0-10mA or 1-5VDC) current signal or voltage signal, you can control the operation. Turn the valve shaft 0~90º with the torque output by the angular stroke to complete the opening and closing action or the adjustment action. All-electronic electric actuator adopts mechatronics structure, with functions such as internal servo operation and position feedback of opening signal, position indication, manual operation, etc., strong function, reliable performance, simple connection, precise control, small size and weight Light, small flow resistance, large flow coefficient, simple structure, good sealing performance. The adjustment range is large. By inputting a current signal or a voltage signal, this is converted into a displacement corresponding to the input signal, and the rotation angle of the valve plate (0-90º any angle) is changed. Therefore, a certain input signal corresponds to a certain rotation angle to achieve proportional action, so there is a better adjustment and control of parameters such as flow.
