A Low Voltage Solenoid Valve is a key component used in various automation systems, particularly when a low voltage power source is preferred. This valve operates based on the principle of electromagnetism, providing control over the flow of liquids or gases through pipelines. By using an electrical current to generate a magnetic field, it opens or closes a valve to regulate fluid movement. In this article, we will explore the working principles, applications, advantages, and key factors to consider when choosing a low voltage solenoid valve.
Working Principle of Low Voltage Solenoid Valves At its core, a low voltage solenoid valve consists of an electromagnet (the solenoid) and a valve mechanism. When electrical current passes through the solenoid, it generates a magnetic field that pulls or pushes a plunger or armature, causing the valve to open or close. This simple yet effective mechanism enables precise control over fluid flow. What differentiates a low voltage solenoid valve from other types is its operation at a reduced voltage—commonly 12V or 24V DC, which is much lower than standard solenoid valves that typically work at higher voltages. The low voltage requirement makes it suitable for systems where power efficiency and safety are priorities, such as in home appliances, industrial automation, and medical devices.
