Understanding Solenoid Valves
What is a Solenoid Valve?
A solenoid valve is an electromechanical device that controls the flow of liquids or gases. It consists of a coil, a plunger, and a valve body. When electrical current passes through the coil, it generates a magnetic field that moves the plunger, opening or closing the valve.
Types of Solenoid Valves
There are several types of solenoid valves, including normally closed and normally open configurations. The choice depends on the specific application and operational requirements. Normally closed valves stop the flow in their default state, while normally open valves allow flow until powered.
