Valves – Definition, Types & Control Mechanism

Valves are defined as devices to control or regulate the commencement, termination, direction and also the pressure or rate of flow of fluid under pressure which is delivered by a compressor or vacuum pump or is stored in a vessel. Valves are technically fittings but are usually discussed as a separate category. In an open valve, fluid flows in a direction from higher pressure to lower pressure.

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 washers and taps in the home. Even aerosols have a tiny valve built in. Valves are also used in the military and transport sectors.
