PSA Programmable Valve
PSA stands for Pressure Swing Adsorption, a process used for hydrogen production, nitrogen production, oxygen production, and CO₂ recovery. PSA valves generally refer to dedicated programmable valves for PSA systems, which are the core components of a PSA unit. They are switched at high frequency under PLC/DCS control to complete the sequential switching of adsorption, pressure equalization, forward release, reverse release, and purging.
