Pneumatic valve?

Instrument air is the purified air used for instruments, brother

I don’t seem to have found this term in any standard reference books. This term is similar to the measurement of lengths used in mechanical installation and maintenance; for some reason, although millimeters should be the standard unit of measurement, it has to be expressed in terms of meters, units, or threads. Terms such as instrument gas, instrument air source, and instrument air source pressure are relatively standard; I’m not sure why it is referred to as “wind”? ? Is it to be more down-to-earth? Is it a code word needed for technological monopoly? ? ? It is unknown. What do you mean by “instrument air line”? ? ? ? ”The term “instrument air line” is not clear; if it refers to “air” for instruments, it probably means the gas used by the instruments. It is commonly referred to as instrument gas in the chemical industry, abbreviated as IG. His standard is for pressurized gases that are dry, at room temperature, and do not undergo chemical reactions with related equipment; common examples include dry air and dry nitrogen. The pressure ranging from 0.4 to 0.8 MPa is what drives the control instruments to function; for example, in pneumatic valve actuators, compressed gas is used for driving the mechanism. Wait. Instrument air – you can think of it as colloquial language. It’s just a way to trick you, to prevent you from finding it in the documents; it’s an artificial secret that’s created for that purpose. I’ve been through it; I despise such behavior and support using standards as a guide.
