Question

Valves that open and close rapidly under the control of electronic circuits are:

1) Solenoid valves
2) Check valves
3) Gate valves
4) Butterfly valves

Answer 1

Solenoid valves are the types of valves that open and close rapidly under the control of electronic circuits and are operated by an electric current through a solenoid.

Step-by-step explanation:

Valves that open and close rapidly under the control of electronic circuits are known as solenoid valves. They are electromechanically operated valves that are controlled by an electric current through a solenoid; they are the common components used for controlling the flow of liquids or gases. Solenoid valves are used in a variety of applications, including in fluid power pneumatic and hydraulic systems, to control cylinders, fluid power motors, or larger industrial valves.

Check valves allow liquid or gas to flow through them in only one direction. Gate valves, on the other hand, are used to start and stop flow and when a straight-line flow of fluid and minimum flow restriction are needed. Butterfly valves are used to regulate flow, typically in large pipe diameters. Each of these valves operates in a different manner and is selected based on the specific requirements of the system or application.
