When a water regulating valve is used to control the head pressure of a water-cooled system, the valve's spring is acting against which pressure to modulate the water flow?
A) Head pressure of the system.
B) Water pressure.
C) Suction pressure.
D) Atmospheric pressure.

Question

Quizplus · Accepted Answer

The purpose of a water regulating valve is to maintain a consistent head pressure in a water-cooled system. The valve's spring is designed to act against the head pressure of the system, which is the pressure of the water at the highest point of the system. By modulating the flow of water, the valve can maintain a consistent head pressure and ensure that the system operates efficiently. Therefore, the best choice is A) Head pressure of the system.
