To start or stop fluid flow

To regulate downstream system pressure

14 / 25

What are the internal elements of a valve collectively referred to as?

Valve body

Valve actuator

Valve trim

Valve packing

15 / 25

What is the main advantage of a ball valve?

It has a compact and lightweight design

It offers precise flow control and throttling capability

It is suitable for high-temperature applications

It provides quick and reliable shut-off with minimal pressure drop

16 / 25

What is the function of the pump casing in a centrifugal pump?

To provide a pressure boundary and direct the flow of the liquid

To regulate the speed and size of the impeller

To support the pump internals and accessories

To prevent leakage between the suction and discharge ports

17 / 25

What is the function of the valve trim?

To prevent leakage between the stem and bonnet of the valve

To provide a tight seal when the valve is closed

To connect the actuator and disk of the valve

To determine the valve's performance and control flow

18 / 25

What is the purpose of a check valve?

To regulate downstream system pressure

To prevent backflow of fluid in a system

To vary the amount of fluid flow

To relieve component or piping over pressure

19 / 25

What is the main difference between positive displacement pumps and centrifugal pumps?

Positive displacement pumps utilize rotational motion, while centrifugal pumps utilize linear motion.

Positive displacement pumps deliver a constant volume of liquid per cycle, while centrifugal pumps deliver a continuous flow.

Positive displacement pumps are suitable for high-pressure applications, while centrifugal pumps are more compact.

Positive displacement pumps require a higher power input compared to centrifugal pumps.
