(From Wikipedia, the free Encyclopedia)
A valve is a mechanical device that regulates the flow of fluids (either gases and liquids) by opening, closing, or partially obstructing various passageways.
There are a number of names for particular type of valve:
A valve doesn't necessarily mean a man-made device; there are several valves inside the human body, for instance in the heart or in veins.
- Cock, colloqual term for a small valve
- Tap (British english), Faucet (US english)
- Bib cock,
- Non-return valve, allows the fluid to pas in one direction only
- Ball cock, Often used as a water level controller (cistern)
- Solenoid valve, electrically controlled
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 "thermionic valves" in Britain.

Valve Software is a video game developer made famous by its first product, Half-Life. Valve went on to create Team Fortress Classic (a mod for Half-Life) and several other extensions to Half-Life. They also took on-board the development of the highly popular Counter-Strike and Day of Defeat Half-Life mods. The company created a stir at E3 in May 2003 by debuting what appeared to be a surprisingly complete Half-Life 2. Valve is also still working on the long-awaited Team Fortress 2 standalone game.
