How Solenoid Valves Work - Basics actuator control valve working principle

The video tutorial explains solenoid valves, detailing their structure, operation, and applications. Solenoid valves consist of a solenoid and a valve body, allowing remote fluid control in systems. They are used in various applications, from household appliances to industrial systems. The video covers the operation of normally open and closed valves, emphasizing the role of electromagnetic fields in their function. It also highlights the efficiency and safety benefits of using solenoid valves in automation.

What is the primary function of the solenoid in a solenoid valve?

• To provide a visual indicator of valve status

• To regulate the temperature of the fluid

• To create an electromagnetic field to operate the valve

• To manually open and close the valve

In which of the following systems are solenoid valves commonly used?

• Only in household appliances

• Only in industrial machinery

• In both household appliances and industrial machinery

• Only in automotive systems

How do solenoid valves contribute to the efficiency of refrigeration systems?

• By autonomously controlling the flow of refrigerant

• By eliminating the need for a compressor

• By reducing the size of the evaporator

• By increasing the temperature of the refrigerant

What happens to the plunger in a normally closed solenoid valve when an electrical current is applied?

• It moves downwards to close the valve

• It moves upwards to open the valve

• It rotates to adjust the flow

• It remains in the same position

What is the role of the spring in a normally open solenoid valve?

• To keep the valve closed when no current is applied

• To keep the valve open when no current is applied

• To provide a backup power source

• To adjust the pressure of the fluid

What determines whether a solenoid coil produces a pulling or pushing force on the plunger?

• The temperature of the environment

• The type of fluid being controlled

• The direction of the current flowing through the coil

• The size of the coil

Which of the following best describes the electromagnetic field in a solenoid valve?

• It is used to cool the solenoid

• It is used to generate electricity

• It is used to create a magnetic force to move the plunger

• It is used to heat the fluid
