Solenoid valves can be powered by AC (alternating current) or DC (direct current) electricity. AC voltage (e.g., 120VAC or 230VAC) reverses direction many times per second, while DC voltage (e.g., 12V or 24V) flows steadily in one direction. This difference affects how the valves behave and where they are used.
Key Differences
- Power Source: AC solenoids run on mains power, while DC solenoids use battery or low-voltage supplies.
- Noise and Vibration: AC coils can buzz or hum; DC coils are quiet.
- Efficiency: AC coils may incur eddy current losses; DC coils are generally more efficient.
- Speed & Heat: DC solenoids typically switch faster and maintain constant force.
Which One to Use? check our DC Solenoid Valve
If you have a reliable DC source, a DC solenoid valve is often easier to control and quieter. Common DC valves (12V/24V) are popular for automotive systems, solar pumps, or battery-powered setups. AC solenoid valves are convenient for fixed installations connected to building wiring. Always match the coil voltage to your supply
