Question 1 of 27070

Q

Most solenoid valves are actuated by __________.

🔍 Key Concepts

• Solenoid valve basic design – what is inside the valve body that makes it open or close? • Difference between mechanical forces (springs, gravity, pressure) and electrical forces • How electrical energy is converted into motion in many control valves

💭 Think About

• Think about what the word "solenoid" refers to in basic electricity and magnetism. • In a typical control circuit on a ship or refrigeration plant, what type of device pulls or pushes a valve stem when power is applied? • Which of the choices would allow the valve to be operated remotely by an electrical signal rather than needing the valve to be moved by fluid or by its own weight?

✅ Before You Answer

• Recall that a solenoid is a specific electrical component you learn about in basic DC/AC theory. • Ask yourself which option can create a controlled linear motion (to move a plunger) when current flows. • Eliminate any options that are usually used only to return a valve to its normal position, rather than to actively drive it open.
