Choke valve, Butterfly valve used to limit air intake in internal combustion engine. (Not to be confused with choke valves used in industrial flow control, above.) Clapper valve: a type of check valve used in the Siamese fire appliance to allow only one hose to be connected instead of two (the clapper valve blocks the other side from leaking out)
Butterfly valve with actuator electric valve - An electrically actuated butterfly valve is a quarter-turn valve controlled by an electric motor. It offers fast and precise flow regulation, remote operation, and versatility for various applications.
A keystone module is a standardized snap-in package for mounting a variety of low-voltage electrical jacks or optical connectors into a keystone wall plate, face plate, surface-mount box, or a patch panel. Keystone modules have a rectangular face of 14.5 mm wide by 16.0 mm high and are held in place with flexible tabs.
These water valves are operated by rotary handles. A valve is a device or natural object that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways.

[1] Globe valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle.
The noise properties of valves at audio frequencies can be modelled well by a perfect noiseless valve having a source of voltage noise in series with the grid. For the EF86 low-noise audio pentode valve, for example, this voltage noise is specified (see e.g., the Valvo, Telefunken or Philips data sheets) as 2 microvolts integrated over a ...
