Discussion on solenoid valve voltage
Thread Content
Dear sea friends, let’s discuss here the advantages and disadvantages of using DC24V and AC220V as the supply voltage for solenoid valves.
In my opinion, the installation distance for AC 220V can be greater, ensuring that no malfunction occurs due to voltage drop.
Based on our factory’s practical experience, when the solenoid valves are located far away from the control room, 220VAC should be used; this prevents voltage drops and ensures that the solenoid valves operate within an appropriate voltage range. The downside is that the high voltage can pose a risk to maintenance personnel during repairs. 24VDC is suitable for short-distance control; at longer distances, the voltage drop can prevent the solenoid valve from operating. Its advantage is safety.
Come in and learn* a bit too. I’m not sure about this. Fellow upstairs, do you have any experience regarding how far the distance is? At what distance would it be advisable to use AC220V?
If 220 V AC power supply is used, the high voltage ensures that the voltage drop caused by the transmission cables does not affect the proper operation of the solenoid valve; therefore, there is no need to consider the voltage loss due to cable resistance, allowing for transmission over long distances. If the supply voltage for the solenoid valve is 24 V DC, the maximum allowable length of the cable must be calculated based on the solenoid valve’s minimum operating voltage.
24 V DC offers better safety and is more convenient for on-site maintenance. The advantages of 220VAC are as mentioned by the people above; 24VDC works perfectly within a range of 200M
DC24V is safer and more convenient. Handling faults at 220V AC on-site is unsafe, especially in the rainy and humid environments of the south.
Of course, there is no problem with the control of programmable valves as mentioned above. However, the reliability of the interlocking actions considered in the interlocking system is greater than the safety level associated with the maintenance of 24V solenoid valves; therefore, 220V solenoid valves need to be used.
I’m here to learn *; thanks for sharing
For distances of up to 200m, 24VDC is more suitable as it facilitates maintenance
