The fine and small valve electric device is a kind of use motor as the driving source and hard DC current as the control signal. It mainly consists of an operator, an amplifier, and an actuator. Using this fine and small valve electric device, its temperature is basically controlled at about 50 ℃.
The essentials of installation and maintenance of fine small valve electric device
So in the face of the many progressive valve electric device products on the market today, what issues must we pay attention to when purchasing?
1. Determine the parameters to be used according to the selected valve electric device. Generally, the parameters are different for different models. Therefore, you must pay attention to whether the parameters are correct when choosing. In addition, motor power, rated current, control loop voltage, etc. should not be ignored.
2. According to the torque of the valve, it is basically the user or the manufacturer to make the selection. The normal opening and closing torque of the valve is determined according to the valve's specifications and working pressure. Therefore, when choosing different specifications of fine and small valve electric devices , This point must be paid attention to.
