High pressure butterfly valves. Knife gate valve dimensions.
High Pressure Butterfly Valves
A valve consisting of a pair of semicircular plates that are attached to a spindle across a pipe and hinged to allow flow only one way
(butterfly valve) a valve in a carburetor that consists of a disc that turns and acts as a throttle
(Butterfly Valve) A water control device with a narrow disc mounted in the water flow path that can be turned so the disc is aligned with the path allowing water to pass by it, or perpendicular to the path to stop the flow.
A valve consisting of a disk rotating on an axis across the diameter of a pipe to regulate the flow, as in the throttles of many engines
A butterfly valve is a valve which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of a ball valve, which allows for quick shut off.
High pressure science and engineering is studying the effects of high pressure on materials and the design and construction of devices, such as a diamond anvil cell, which can create high pressure.

A high-pressure area is a region where the atmospheric pressure at the surface of the planet is greater than its surrounding environment. Winds within high-pressure areas flow outward due to the higher density air near their center and friction with land.

Here's a pretty cool 935 engine. Take your foot off the throttle, these little butterflies open, turbines keep rolling high speed, low pressure air whooshes though... until you need the power, and schlink! the valves close and all that boost goes into the intakes...
I believe this is a Porsche Kremer 935K-3, wearing #79, driven now by Woody Perkins.
