Saturated vapor pressure Pv is closely related to temperature
The occurrence of flash evaporation is determined by the process and is inevitable!

Corrosion/Abrasion
Factors affecting the degree of valve damage under flash evaporation conditions
Saturated vapor pressure Pv is closely related to temperature
Markco determined through experiments:
High recovery (low recovery coefficient)
Valves are more prone to cavitation
Choose a valve structure with high recovery coefficient FL
Through strict calculation, increase the reasonable number of step-down stages
Reasonable selection of valve materials
