AC vs DC Solenoids for Irrigation Systems: What’s the Difference?

Choosing the right solenoid is critical to the efficiency and longevity of your irrigation system. That’s why it’s important to understand the differences between AC and DC irrigation solenoids, and how those differences impact their performance and applications.

AC Solenoids

AC solenoids are designed to run on alternating currents, which are found in standard AC power sources. They work by utilizing an electromagnet that generates a linear motion when energized by the alternating current. This motion controls the opening and closing of the valve, regulating the flow of water through the irrigation system. AC solenoids are commonly used in irrigation systems that are powered by standard AC electricity.

The primary advantage of AC solenoids is their high reliability. AC power is constant and stable, which means that an AC solenoid will operate consistently and predictably over time. Additionally, AC solenoids typically require less maintenance than DC solenoids, which can be more prone to wear and tear over time due to the differences in electromagnet design.

DC Solenoids

DC solenoids, on the other hand, are designed to run on direct currents, which are found in batteries or solar panels. They also utilize an electromagnet, but the linear motion generated is unidirectional. When energized by direct current, the DC solenoid produces a pulling or pushing motion without reversal. DC solenoids are commonly used in irrigation systems that are powered by batteries or solar panels, or in remote locations where access to AC electricity is limited.

The primary advantage of DC solenoids is their portability and versatility. Because they don’t require a standard AC power source, they can be used in remote locations or in areas where access to AC electricity is limited.

Choosing the Right Solenoid for Your Irrigation System

When choosing between AC and DC solenoids, it’s important to consider the power source available and ensure compatibility with the controller and other system components. If your irrigation system is powered by standard AC electricity, an AC solenoid will be the right choice. If your irrigation system is powered by a battery or solar panel, a DC solenoid will likely be the right choice.

If you are repairing an Irrigation system, you also need to know the manufacturer and/or thread style. Hydro-Rain offers solenoid adapters allowing you to use our latching solenoid or HRJ-SD2-RP with virtually any valve!

In conclusion, choosing the right solenoid for your irrigation system can make a big difference in its efficiency and longevity. Understanding the differences between AC and DC solenoids, and their applications, is an important first step. At Hydro-Rain, we are committed to quality and customer satisfaction.
