Types of Valves 

Please click for general information on basic valve types or specific valve types


Valves are quite diverse and may be classified into a number of basic types. Valves may also be classified by how they are actuated:

Basic types Valves can be categorized into the following:

Specific valve types:

The valve is a unit that regulates the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. Valves are technically pipe fittings, but sometimes referred to in a different category. In an open valve, fluid flows in a direction from higher pressure to lower pressure.

Valves are used in a variety of contexts, including industrial, government, military, commercial, residential, and transport.

The industries in which the majority of valves are used are oil and gas, power generation, mining, water reticulation, paper mills, refinery, sewerage and chemical manufacturing.

Common valves are plumbing valves, for example taps for hot and cold tap water are the most visable types of valves. Other valves experienced on a daily basis include gas control valves on cookers, small valves fitted to washing machines and dishwashers, and safety devices fitted to hot water systems.

Valves may be operated manually, by a hand wheel, lever or pedal. 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 type 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.
