Fuel Pressure Gauge Install

Looking around through here, I noticed several pics of a valve installed in line to the fuel pressure gauge. What is the purpose of this?

You use the valve for two reasons--1 if the line ever breaks you can turn off the fuel flow, and 2 you regulate the "opening" down to minimize the pulsations that you will see in the gauge from the fuel pump.
