In a cone valve chest, the windchest is divided into 'stop channels' instead of key channels. Each stop channel admits wind to all the pipes in a rank when the corresponding stop is activated. Each key is connected to a set of cone valves, one for each rank. The cone valves admit or deny wind to all the pipes of each rank for a particular note.
The vents of the Redoutable are under the casing. The square openings in the casing are limber holes to facilitate draining the superstructure. In submarine technology a vent is a valve fitted to the top of a submarine's ballast tanks to let air escape from the top of the ballast tank and be replaced by water entering through the opening(s) called "flood ports" or "floods" at the bottom of the ...
Schematic cross section of a pressurized caisson. In geotechnical engineering, a caisson (/ ˈ k eɪ s ən,-s ɒ n /; borrowed from French caisson 'box', from Italian cassone 'large box', an augmentative of cassa) is a watertight retaining structure [1] used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, [2] or for the repair of ships.
This valve prevents the release of vapors during very small changes in temperature, barometric pressure, or liquid level. [1] Fixed roof tanks without breather valves will generally be freely vented; [2] thus the emissions from a fixed roof tank can be non-trivial. Gauge hatches, sample wells, float gauges, and roof manholes provide ...
Fixed cone valves are able to handle heads up to 300 m. Hollow jet valves are a type of needle valve used for floodgate discharge. A cone and seat are inside a pipe. Water flows through an annular gap between the pipe and cone when it is moved downstream, away from the seat. Ribs support the bulb assembly and supply air for water jet stabilization.
English: Diagram of a water distribution system. Inlet water goes through a pumping station. The water is delivered to the top of a water tank. Water pressure created by gravity and delivered to water mains. Water mains are connected to fire hydrants and service lines which are pipes that connect a water main to a building.

Also, the tortuous S-shaped path the water is forced to follow offers a significant obstruction to the flow. For high pressure domestic water systems this does not matter, but for low pressure systems where flow rate is important, such as a shower fed by a storage tank, a "stop tap" or, in engineering terms, a "gate valve" is preferred.
