Key Aspects of Pressure Control:
Components: Systems typically utilize pressure sensors (diaphragms, pistons), controllers (PCBs), and actuators/valves to maintain stability.
Methods:
Upstream Control: Regulates pressure by controlling the amount of gas/fluid entering a system (e.g., using a Mass Flow Controller).
Downstream Control: Controls pressure by adjusting the outflow or restricting the exhaust/pump speed.
Common Valves: Relief valves (limit maximum pressure), Reducing valves (lower pressure), Sequence valves (order operations), and Counterbalance valves.
