A Low Voltage Solenoid Valve is a critical component used in various industries to control the flow of fluids or gases. As the name suggests, these valves operate on low-voltage electrical signals, typically 12V or 24V, to regulate fluid movement. These valves provide a reliable and efficient method for automating fluid flow control, making them invaluable in systems where precise control is necessary. In this article, we will explore the working principle, applications, and advantages of low-voltage solenoid valves.
Working Principle of Low Voltage Solenoid Valves
At the heart of a low-voltage solenoid valve is an electromagnet, or solenoid, which is a coil of wire through which an electric current is passed. When the current flows through the coil, it generates a magnetic field. This magnetic field acts on a movable iron core or plunger within the valve. Depending on the design, the movement of the plunger either opens or closes the valve, allowing or stopping the flow of the fluid.
When the solenoid is energized, the plunger moves to the open position, permitting fluid to flow through the valve. When the current is cut off, the plunger returns to its closed position due to a spring mechanism, halting the flow of fluid. In some valve designs, the solenoid can hold the valve in an open or closed position even without continuous power, known as a bistable valve.
