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 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) flowing in one direction, but is pushed open by flow in the opposite direction. This is called check valve, as it prevents or "check" 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 and pressure control to dish and clothes washer and taps in the home. Even aerosols have a tiny valve built in. Valves are also used in the military and transportation sectors.

Valves are found in virtually every industrial process, including water and sewage processing, mining, power generation, processing of oil, gas and petroleum, food manufacturing, chemical and plastic manufacturing and many other fields.

People in developed nations use valves in their daily lives, including plumbing valves, such as tap for tap water, gas control valve on cookers, small valves fitted to washing machines and dishwasher, safety devices fitted to hot water systems and poppet valves in car engines.

In nature there are valves, for example one-way valves in veins controlling the blood circulation, and heart valves controlling the flow of the blood in the chambers of the heart and maintaining the correct pumping action.

Valves may be operated manually, either by 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 requirement.
