Gate Valves, are a type of valve that opens by raising a barrier (gate) out of the fluid path. Gate valves require little space
along the Pipe axis and are fully
Almost never restricts fluid flow when opem The gate faces can be parallel, but are most commonly wedge-shaped (to be able
to apply pressure on the sealing surface).
Gate valves are used to close the flow of liquids, not for flow regulation. When fully open, a typical gate valve has no
obstructions in the flow path, resulting in very low flow resistance.
As the gate moves, the dimensions of the open flow path typically change in a non-linear fashion. This means that flow does
not vary evenly with stem travel. Depending on the structure, a partially open gate vibrates due to fluid flow. Gate valves are
primarily used for larger pipe diameters (from 2 inches to the largest) because they are simpler to construct than other types of
