The Low Voltage Solenoid Valve is an essential component in many modern automated systems, where it serves as the key to controlling the flow of fluids such as gases, liquids, and steam. These valves operate based on electromagnetic principles and provide a reliable solution for industries ranging from manufacturing and HVAC to water treatment and robotics. By utilizing low voltage signals, these valves offer enhanced safety and energy efficiency, making them an increasingly popular choice in a variety of applications.
Working Principle The operation of a Low Voltage Solenoid Valve is governed by the interaction of an electrical current and a magnetic field. When an electric current passes through the coil of the solenoid, it generates a magnetic field, which moves a plunger or valve stem. This movement opens or closes the valve, thereby controlling the flow of fluid through the system. The valve can be either normally open (NO) or normally closed (NC), depending on the design. In a normally closed valve, the spring holds the valve in the closed position, and the electromagnetic force is required to open it. Conversely, in a normally open valve, the electromagnetic force is needed to close it.
