VALV/vælv/

A valve is a device that opens and closes to control the flow of liquid, gas, or blood: a safety valve; a heart valve. Tap is everyday for water; tap is not precise enough in a circuit diagram. Name the valve in the circuit diagram, then the fluid. Mix-up: valve vs value; valve vs vole; do not write valve for a solid pipe with no opening named.

Meaning

A device that opens and closes to control the flow of liquid, gas, or blood.

Examples

• “Name the valve in the circuit diagram, then the fluid, the physics paper said.”
• “A heart valve featured in the biology diagram, which is still a named flap — quote the chamber if given.”

Good to know

a safety / one-way / heart valve; valve in a circuit. Everyday: tap (water). Trap: value / a plain pipe. Physics, biology, and DT. Controls flow — name the fluid and the type.
