What Is Flashing?

Flashing is a condition that occurs with liquid flow where the pressure falls below the vapour pressure and remains below it. There are then two phases flowing (i.e. liquid and vapour) downstream.

Severe damage can occur inside a valve due to erosion caused by the impact of liquid droplets travelling at high speeds.
