There are air sources, pressure reducing valves, and electrical devices on the pipeline. Is it a quick-open damper?
With insulation, the medium should be gas, such as steam； Judging from the insulation shell, the distance between the valve flanges is not large, so it should be a butterfly valve. ； Look at the actuator and confirm it should be a butterfly valve. ； Judging from the opening power, it should be pneumatic. ； Is it the steam regulating valve of the turbine compressor?
