Low voltage solenoid valves are integral components in various industries and applications, playing a critical role in controlling the flow of fluids or gases. These valves function using a solenoid, an electromechanical device that operates when an electrical current passes through it. When the current flows through the solenoid, it creates a magnetic field that either opens or closes the valve, allowing or blocking the passage of fluids. As the name suggests, low voltage solenoid valves are designed to operate at lower electrical voltages, typically ranging from 12V to 24V, as opposed to higher voltage counterparts, making them a preferred choice in many applications where safety, energy efficiency, and system reliability are of paramount importance.
Design and Working Principle A low voltage solenoid valve consists of several key components: the solenoid coil, the plunger (or armature), the spring, and the valve body. When a low voltage current is applied to the solenoid coil, it generates a magnetic field that attracts the plunger. This movement either opens or closes the valve seat, depending on the valve’s design. The spring helps in returning the plunger to its default position when the current is turned off, thus controlling the flow of fluids or gases through the valve. The ability to control the valve with a low voltage electrical signal is one of the significant advantages of these solenoid valves. It allows for more precise and efficient operation, reducing energy consumption and minimizing the risk of electrical hazards in sensitive environments.
