A DC solenoid valve is an electromechanical device used to control the flow of fluid or gas in a system. The valve operates by using a direct current (DC) electric signal to actuate a magnetic field within the solenoid coil. When the current passes through the coil, it creates a magnetic force that pulls a plunger or armature to either open or close the valve. This allows for precise control over fluid or gas flow, making these valves ideal for applications requiring high reliability and accuracy.

    DC solenoid valves are typically used in systems that operate on low power consumption, providing an energy-efficient solution compared to their AC counterparts. They are found in various industries, including HVAC systems, water treatment facilities, and automated machinery, due to their efficiency and reliability.
