The term 'Flow Regulator' refers to two different devices used to control the flow of liquids or gases. The first device is a VALVE, which is a mechanical device that controls the flow of a liquid or gas by opening, closing, or partially obstructing a passageway. The second device is a FAUCET, which is a device used to control the flow of water from a pipe or other source. Both valves and faucets are used to regulate the flow of liquids or gases in order to maintain a desired pressure or flow rate.
