How do solenoid valves function?

• A. By manipulating fluid viscosity
• B. By using an electric coil to shift a plunger
• C. By altering the temperature of the fluid
• D. By adjusting pressure levels

Answer: (B)

Solenoid valves function through the use of an electric coil that generates a magnetic field when electricity flows through it. This magnetic field acts on a plunger or armature within the valve, causing it to move. When the coil is energized, the plunger is shifted, either opening or closing the valve to control the flow of fluid. This mechanism enables rapid and precise control over fluid movement in various applications, such as controlling water flow in irrigation systems or regulating gas in industrial processes. The electric coil's operation allows for remote control and automation, which is a significant advantage in many systems.
