Synonym discussion

Sense: noun/1

While all three terms refer to multiple valves working together, they differ in scope and formality. Valving (the headword) is the most technical and collective — it names the abstract concept of how valves are positioned and connected as part of a larger design. Valve arrangement is a more everyday phrase that describes the physical layout of valves in specific positions. Valve system is broader and can include the valves themselves along with the pipes, controls, and regulators that work with them — for example, a sprinkler valve system includes the timer and pressure regulator. Valve assembly usually refers to a pre-built unit where several valves are joined together as one component, such as a valve assembly in a car engine's cylinder head. When describing a technician's work, valving focuses on the design logic; valve arrangement focuses on the physical layout; valve system includes the supporting hardware.

Etymology

LatinEnglish

Valving is formed from the noun valve (which comes from Latin 'valva', meaning a leaf of a folding door or a part that opens and closes) plus the suffix '-ing', which here creates a collective technical noun describing the system or arrangement of valves as a whole.
