A globe valve installed in the feed water line has a pressure from the feed water pump affected in what way?

The pressure in a globe valve installed in the feed water line is highest under the valve disc. This occurs because the flow of water must pass through the valve from the inlet side, which is below the valve disc, as the valve opens and closes to regulate the flow.

In this configuration, when the feed water pump is operating, it creates pressure in the feed water line that is transmitted to the area underneath the valve disc. As the water flows, the pressure is exerted upward against the disc. This pressure is essential for the valve's operation and performance, affecting factors such as the flow rate and the force required to open or close the valve.

Understanding this principle is crucial for maintaining the system's efficiency and ensuring that the valve operates correctly under various pressure conditions.
