Interview Questions and Answers

Valve types include ball valves, gate valves, globe valves, and butterfly valves.

• Ball valves: used for on/off control without pressure drop

• Gate valves: used for full flow or no flow applications

• Globe valves: used for regulating flow in pipelines

• Butterfly valves: used for throttling flow in large pipelines

Valve is a device that regulates, directs, or controls the flow of a fluid (such as gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways.

• Valves are commonly used in plumbing, irrigation, industrial, and automotive applications.

• There are different types of valves such as ball valves, gate valves, globe valves, and butterfly valves.

• Valves can be manual or automatic, depending on the application.

• Valves play a crucial ro...read more

GD&T symbol stands for Geometric Dimensioning and Tolerancing, a system for defining and communicating engineering tolerances.

• GD&T symbols are used to specify the allowable variations in form, size, and orientation of features on a part.

• Examples of GD&T symbols include concentricity, perpendicularity, and flatness.

• GD&T helps ensure that parts fit together properly and function as intended.

• It is commonly used in engineering drawings and manufacturing processes.

Control valves are used to regulate the flow of fluids in a system by varying the size of the flow passage.

• Control valves are essential components in process control systems.

• They can be used to control flow rate, pressure, temperature, or liquid level.

• Control valves can be operated manually, pneumatically, electrically, or hydraulically.

• Examples include globe valves, butterfly valves, ball valves, and diaphragm valves.

Control valves are used to regulate the flow, pressure, temperature, or level of a fluid in a process system.

• Control flow rate in pipelines

• Regulate pressure in a system

• Control temperature in a heat exchanger

• Maintain level in a tank

• Used in industries like oil & gas, chemical, water treatment
