Solenoid Valves
A solenoid valve is an electromechanically operated valve that uses an electric current to open or close a valve, controlling the flow of a fluid (liquid or gas). They're widely used for automated fluid control because they offer fast, safe, and reliable switching.
How It Works
The core components of a solenoid valve are the solenoid (an electromagnetic coil) and the valve body.
When an electric current is applied to the solenoid coil, it generates a magnetic field. This magnetic field either pulls or pushes a plunger or piston against a spring.
Normally Closed (NC) Valves: The valve is closed by default, with the plunger being held against the valve's orifice by a spring. When the coil is energized, the magnetic force lifts the plunger, opening the valve and allowing fluid to flow.
Normally Open (NO) Valves: The valve is open by default. When the coil is energized, the magnetic force pushes the plunger down to seal the orifice, stopping the flow.
Once the electrical current is removed, the magnetic field disappears, and the spring returns the plunger to its original position, restoring the valve to its default state.
