A gatehouse, gate house, outlet works or valve house for a dam is a structure housing sluice gates, valves, or pumps (in which case it is more accurately called a pumping station). Many gatehouses are strictly utilitarian, but especially in the nineteenth century, some were very elaborate.
Within the gate valve, there is a gatelike disk that moves up and down perpendicular to the path of flow and seats against two seat faces to shut off flow. The velocity of the fluid against a partly opened disk may cause vibration and chattering which will ultimately lead to damage to the seating surfaces. This is a common way that gate valves ...
Gate valves may have flanged ends drilled according to pipeline-compatible flange dimensional standards. Gate valves are typically constructed from cast iron, cast carbon steel, ductile iron, gunmetal, stainless steel, alloy steels, and forged steels. All-metal gate valves are used in ultra-high vacuum chambers to isolate regions of the chamber ...

The work begins with a detailed account of the climate of the western United States, founded on Smithsonian climate data and Powell's personal observations from his own extensive surveys of the region. [2] Powell describes the extent and potential of three main types of land in the region: irrigable lands, timber lands, and pasturage lands.

Ring jet valves are similar to fixed cone valves, but have an integral collar that discharges water in a narrow stream. They are suitable for heads up to 50 m. They are suitable for heads up to 50 m. Jet flow gate , similar to a gate valve but with a conical restriction prior to the gate leaf that focuses the water into a jet.
