What Is A Solenoid Valve?

The video tutorial explains solenoid valves, highlighting their distinctive structure and functionality. Solenoid valves consist of a valve body and a solenoid, allowing for remote and autonomous control of fluid flow in systems. The tutorial covers the operation of direct operated valves, emphasizing the role of electromagnetic fields. It also distinguishes between normally open and normally closed valves, detailing the internal components like the armature, plunger, and spring, and how they function to control fluid flow.

What is the primary function of solenoid valves in engineering systems?

• To increase the temperature of fluids

• To autonomously and remotely control fluid flow

• To decrease the pressure of gases

• To manually control fluid flow

How does the solenoid coil operate the valve?

• By creating a magnetic field

• By rotating the valve body

• By increasing fluid pressure

• By decreasing fluid temperature

What happens when an electrical current is passed through the solenoid coil?

• The system shuts down

• A magnetic field is generated

• The valve closes automatically

• The fluid flow stops

In a normally closed solenoid valve, what role does the spring play?

• It opens the valve

• It increases fluid pressure

• It closes the valve

• It regulates fluid temperature

Where is the plunger placed in a solenoid valve to ensure maximum efficiency?

• At the edge of the coil

• Outside the magnetic field

• In the center of the coil

• Above the solenoid
