Electric Butterfly Valve
Working Principle:
Electric butterfly valve is an automatic regulating valve used in automatic control system. The principle of electric control is to control and guide the opening and closing of the valve according to the power signal. The working power usually includes: AC220V, AC380V, DC24V, and the input signal includes 4~20mA, 0~10V and other weak current signals.
Application:
The electric butterfly valve is a multi-function valve with the functions of a check valve, a control valve and a globe valve, so it is widely used. Usually, the electric butterfly valve is equipped with a manual control device. When the power signal is abnormal or the power is cut off, the butterfly valve is prevented from emergency operation by the manual device, so as to ensure the normal operation of the pipeline system. Electric butterfly valves are used in many fields, such as production pipelines in petroleum, chemical and other industries.
