The valve electric device is a device that uses electric energy to open and close the valve. It is a device that controls the operation of the control elements in the open-loop and closed-loop control systems. It can be divided into electric valve and electric actuator. As an important energy equipment, valve electric device is widely used in petroleum, chemical, electric power, metallurgy and other fields, and is one of the commonly used equipment in pipeline control system.
Electric valve device is mainly used for valve switch, electric valve device is suitable for control of gate valve, globe valve, etc.
The valve electric device should match the motor model. If the output torque does not have enough corresponding margin, it is easy to cause damage to the motor and electrical protection failure during overload operation. So do you know the working principle of the valve electric device? The micro switch in the valve electric device is a key component of the control mechanism. When the valve exceeds the stroke position, the micro switch cuts off the power supply and plays an overload protection role.
