When the electric actuator is powered on, it is found that the power indicator is off, the servo board has no feedback, and the signal does not work.
Valve electric device is an indispensable actuator in the industry. It can realize remote control and near-control automatic function through the control box of external power supply or external input signal, computer DCS, computer PLC and other signal sources.
The advantages are convenient energy access, fast signal transmission, long transmission distance, convenient centralized control, high sensitivity and precision, and electric adjustment.
The valve electric device is the execution unit of many combined control instruments, which can accept unified standard signals, transfer these models into standard parameters, and output sufficient mechanical torque. To drive the valve to complete various actions. So what happens during the use of small and small electric execution, how to eliminate it?
Valve electric devices are also called electric actuators. They are called different in different regions. In some industrial pipeline industries, they are basically called valve electric devices. In the instrument industry, they are called valve electric devices. But in general, its function is the same regardless of the actuator mechanism.
There are many brands of valve electric devices in the market, so there are different types of actuator products, but the torque values vary according to the manufacturing level, structure and material selection of the manufacturer. Therefore, when the valve is selected, the manufacturer should confirm the large torque value of the valve opening and closing.
