Valve Introduction:

A valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries)

by opening, closing, or partially obstructing various passageways. Valves are technically valves fittings,

but are usually discussed as a separate category.

In an open valve, fluid flows in a direction from higher pressure to lower pressure.

The simplest, and very ancient, valve is simply a freely hinged flap which drops to obstruct fluid (gas or liquid) flow

in one direction, but is pushed open by flow in the opposite direction. This is called a check valve, as it prevents or

"checks" the flow in one direction

Valves have many uses, including controlling water for Irrigation, industrial uses for controlling processes, residential

uses such as on / off & pressure control to dish and clothes washers & taps in the home. Even aerosols have a tiny

valve built in. Valves are also used in the military & transport sectors.

Valves are found in virtually every industrial process, including water & sewage processing, mining, power generation,

processing of oil, gas & petroleum, food manufacturing, chemical & plastic manufacturing and many other fields.

People in developed nations use valves in their daily lives, including plumbing valves, such as taps for tap water,

gas control valves on cookers, small valves fitted to washing machines and dishwashers, safety devices fitted to hot

water systems, and poppet valves in car engines

In nature there are valves, for example oneway valves in veins controlling the blood circulation, & heart valves

controlling the flow of blood in the chambers of the heart and maintaining the correct pumping action.

Valves may be operated manually, either by a handle, lever, pedal or wheel. Valves may also be automatic, driven

by changes in pressure, temperature, or flow. These changes may act upon a diaphragm or a piston which in turn

activates the valve, examples of this type of valve found commonly are safety valves fitted to hot water systems or

boilers.

More complex control systems using valves requiring automatic control based on an external input (i.e., regulating

flow through a pipe to a changing set point) require an actuator. An actuator will stroke the valve depending on its

input and set up, allowing the valve to be positioned accurately, and allowing control over a variety of requirements.
