Description of electric valve connection
Electric valve wiring methods are classified according to different use requirements and different field conditions,
lug type butterfly valve, ductile iron, center lined,
and the wiring methods used by electric actuators with different functions are also different. The user should have an understanding of the relevant knowledge of the wiring, so as to avoid unnecessary failures. On the one hand, the entire circuit will be short-circuited; On the other hand, it may cause huge economic losses caused by the burning of the machine, or even more serious Accident!
Electric valve actuators can generally be divided into AC (AC110V, AC220V, AC380V) and DC (DC24V, DC12V) according to the power supply voltage. According to the control method, they can be divided into active switch type, passive switch type, potentiometer type, explosion-proof type, and adjustable type Wait.
