A valve is a device for controlling the passage of fluid or air through a pipe, duct, etc, by opening, closing, or partially obstructing various passageways. The simplest valves are one-way-flap mechanisms that allow flow in one direction and shut with back-flow pressure to stop flow in the direction of origin.
The simplest, and very ancient, valve is simply a freely hinged flap which swings down to obstruct fluid (gas or liquid) flow in one direction, but is pushed up by the flow itself when the flow is moving in the opposite direction. This is called a check valve, as it prevents or "checks" the flow in one direction.

A valve is a device that shuts off, starts, or controls the flow of a fluid. A simple type of valve consists of a hinged flap that drops to block fluid flow in one direction but is pushed open by flow in the other direction. When the steam pressure reaches 15 psi, the safety valve opens and excess steam escapes.
