but if its a sewage treatment plant for a residential area, where i imagine its a practically safe area from corroding gases ( I assumed only the formation of CO2 gases from the plant) because here in India most of the population choose aerobic bio treatment than anaerobic. Lets say for controlling just the flow in a pressurized line . would you suggest a air-operated butterfly valve or a electrically-operated system?
