What is an expansion valve?

The purpose of an expansion valve, also known as an over-pressure valve, is to release excess pressure in the line once the line has been shut closed. This is required to release the pressure in the espresso machine lines due to heat causing water expansion. Some of these valves are adjustable, and correct adjustment is crucial as these valves directly affect espresso extraction.
