Which statement about air regulating valves is true?

A. Most often located directly upstream of the compressor.
B. Intended to maintain a level pressure between 0 and the full line pressure.
C. Intended to react to increases in pressure, not decreases in pressure.
D. Most often located at the outlet of an actuator.



Answer :

Final answer:

Regulating valves are designed to maintain pressure levels and are crucial in process design and operational efficiency.


Explanation:

Regulating valves are intended to maintain a level pressure between 0 and the full line pressure. They are not most often located directly upstream of the compressor but can be found in supply lines connected to basins, tanks, and reservoirs to prevent overflow of fluid and maintain a constant fluid level.

These valves are essential in process design to control pressure and flow, ensuring smooth operations. When designed properly, valves, actuators, and control systems work together to regulate the flow of fluid accurately and maintain system efficiency.
