How is the flame arrestor valve of the air compressor controlled during normal production? How is an emergency shutdown controlled?
In normal operation, the small flare valve is controlled automatically while the large valve is controlled manually; in emergency situations, the larger valve opens, and the smaller one opens automatically
Which type of process is it part of? It depends whether it is a torch release valve or an anti-surge control valve; different production processes have different requirements. For such questions, a specific analysis is required; otherwise, the answer will not be relevant!
Is your flame arrestor valve controlled only by DCS? How is it controlled when the ITcc stops?
I asked clearly: how is the control circuit for the flare valve of your compressors regulated during normal production? How is it controlled during an emergency shutdown?

During normal production, the flare valves of our compressors are all in manual mode； During an emergency shutdown, the large valve opens by 30% automatically, after which both the large and small valves can be adjusted manually.
