Gate valves are primarily used to permit or prevent the flow of liquids, but typical gate valves shouldn't be used for regulating flow, unless they are specifically designed for that purpose.

The weirmaster would walk up to the hexagonal valve house, constructed to the same design as BCN tollhouses, and operate the gate valves to release water from Chasewater reservoir into the canal.
33.
A "'gate valve "', also known as a "'sluice valve "', is a valve which opens by lifting a round or rectangular gate / wedge out of the path of the fluid.
34.
The engineers realized the previous flaws of the artesian well plan and soon added a gate valve to the well to control the flow of water, giving Aberdeen its first working water supply.
35.
For other devices such as ball or gate valves, plastic pieces which either fit against the pipe and prevent movement, or clam-shell style objects, which completely surround the valve and prevent its manipulation are used.
36.
A basic surface tree consists of two or three manual valves ( usually gate valves because of their flow characteristics, i . e . low restriction to the flow of fluid when fully open ).
37.
The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restriction is desired.
38.
As built, the dam is a stone structure, with large cast-iron waste pipes controlled by large gate valves in the top of the dam next to the spillway went through the bottom of the dam.
39.
The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restriction is desired.
40.
For example, opening the gate of a gate valve ( of rectangular cross section ) by 1 mm for 10 seconds yields the same absement of 10 mm�s as opening it by 5 mm for 2 seconds.
