A DC Solenoid Valve is a critical component in various fluid control systems, playing a pivotal role in automating processes that involve the flow of liquids or gases. This versatile device uses an electromagnetic coil powered by a direct current (DC) voltage to control the opening and closing of a valve. In this article, we will explore the functionality of DC solenoid valves, their common applications, and the advantages they offer in different industries.

What is a DC Solenoid Valve? A DC Solenoid Valve operates based on the principle of electromagnetism. When an electric current flows through the solenoid coil, it generates a magnetic field that activates the valve mechanism, either opening or closing the valve. The valve can be either normally open (NO) or normally closed (NC), depending on the design. In a normally closed DC solenoid valve, the valve remains shut when there is no current, and it opens when current is applied. Conversely, in a normally open solenoid valve, the valve stays open without current and closes when the solenoid is activated.
