understanding dc solenoid valve： applications and working principles
Release time:2025-11-17 10:23:04
The DC Solenoid Valve is a type of electromagnetic valve that is widely used in automation systems, fluid control, and various industries. Operating through the principle of electromagnetism, this valve regulates the flow of liquids or gases by opening or closing its internal passage. This article explores the working principles, features, applications, and benefits of DC solenoid valves.
Working Principle of a DC Solenoid Valve
At the core of the DC solenoid valve is the electromagnetic coil. When direct current (DC) flows through this coil, it generates a magnetic field. The magnetic field then acts on the valve plunger or core, which moves within the valve body. Depending on the design of the valve, the movement of the plunger either opens or closes the valve, controlling the flow of the fluid.
When the DC power supply is turned on, the coil is energized, and the valve is actuated, allowing fluid to pass through the valve. When the current is turned off, the magnetic field collapses, and the valve returns to its default position—either closed or open—depending on the valve's design.
