#REDIRECT valve |
A valve is a device that regulates the flow of both gases and liquids throught the opening and closing of passageways. Because their effect on a flow of electrons is analogous to the fluid devices, the electronic devices known in the US as `vacuum tubes' are called `valves' in Britain. |
