What does valving mean?
Valving is the activity of regulating, directing, or cutting off the movement of a fluid or gas through a valve. It is used especially in descriptions of engines, pipelines, pumps, laboratories, and industrial machinery. The word can refer to the operation of adjusting a valve, as when a technician valves an intake, or to the broader use of valves in controlling pressure and flow. In technical contexts, valving is precise and functional: it suggests deliberate adjustment rather than simply turning something on or off. Figuratively, it can describe the careful management of anything that flows, such as money, information, traffic, or emotional expression. Because a valve regulates movement through an opening, the word carries a practical, mechanical quality. It is useful when one wants to emphasize control, calibration, or the gradual adjustment of a system's behavior rather than merely its operation.
To control, regulate, or shut off the flow of a fluid or gas by operating a valve.
"The pilot carefully valved the fuel line to maintain steady pressure."
Common in technical and industrial contexts; also used figuratively for regulating any flow or resource.
The act or process of operating or using a valve to regulate the flow of a fluid or gas.
"The smooth valving of the system kept pressure from rising too quickly."
Less common than the verbal use and usually tied to machinery, engineering, or technical processes.
The plural is possible but uncommon, as the noun is normally used in the singular or with an article.
"The engineers documented the valvings of each valve during the test."
Valving turns a simple opening and closing device into a precise instrument for controlling the movement of liquids and gases.

Etymology of valving
Valving is formed from the English word valve, which came through Middle French from the Latin valva, meaning a door or folding leaf. The modern technical sense developed from the use of valves to control the flow of water, gas, steam, and other substances through pipes and machines. Valving follows the usual English formation in -ing, indicating an ongoing action or the gerund.
How valving is actually used
Valving is chiefly a technical or descriptive term. It is common in engineering, machinery, plumbing, and industrial processes, but it is also used figuratively for the precise control of a flow, process, or resource.
Easily confused with valving
A valve is the device that regulates a flow, whereas valving is the act of operating or using such a device.
