As part of the material exchange process, the valve is often used as a measuring or metering device.

Famous quotes containing the word industry:
“You must, to get through life well, practice industry with economy, never create a debt for anything that is not absolutely necessary, and if you make a promise to pay money at a day certain, be sure to comply with it. If you do not, you lay yourself liable to have your feelings injured and your reputation destroyed with the just imputation of violating your word.”
—Andrew Jackson (1767–1845)
