The wiring methods for electric valves are categorized based on different application requirements and on-site operating conditions. The wiring methods chosen for electric actuators with different functions also vary. Users should have some understanding of the relevant wiring knowledge to avoid unnecessary faults. On the one hand, these faults can lead to short-circuit issues in the entire circuit; on the other hand, they may cause significant economic losses due to the burnout of machines, and even lead to more serious incidents.
