A faucet or a tap (also spigot) is a valve controlling the release of a liquid or gas. Turning a valve knob or lever adjusts flow by varying the aperture of the control device in the valve assembly. The result when opened in any degree is a choked flow. Its rate is independent of the viscosity or temperature of the fluid or gas in the pipe and depends only weakly on the supply pressure, so that flow rate is stable at a given setting.
A schank is the long, narrow part of a tool connecting the handle to the operational end. A shank is frequently used with a faucet or dispensing control knob or handle. The unthreaded part of the shaft of a bolt is also called the shank.
A shutoff is a device (a gate, valve, shaft, cam or breaker) designed to interrupt the flow of a solid, liquid or a gas and in electrical components, the flow of current. Shutoffs may also be used as brakes in slowing or stopping the motion of a system or component. Shutoffs may be manually or automatically actuated in response to connected signaling or sensing systems.
A valve is a device that regulates, directs or controls the flow of a fluid (gases, steam, liquids, fluidized solids or slurries) by opening, closing or partially obstructing various passageways. In an open valve, fluid flows in a direction from higher pressure to lower pressure.
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. 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. They can be electromechanical actuators such as an electric motor or solenoid, pneumatic actuators which are controlled by air pressure or hydraulic actuators which are controlled by the pressure of a liquid such as oil or water. 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.
