In this episode, we're breaking down how CO2 high pressure valves (HPV) work. We'll cover basic operation and design, as well as tips on proper settings, sensor placement and protection, fine-tuning for climate, and using trend graphs to diagnose issues. We'll also discuss the role of an HPV in receiver/flash tank protection versus gas cooler control across transcritical, transition, subcritical, and holdback modes.
