A device installed in every part of a pipeline to adjust the flow of fluid (flow rate).
While it is often recognized as a type of valve, it displays the following differences.
– While there are no leaks when a valve is fully closed,
there are leaks when a damper is fully closed.
– A damper is compatible with many shapes (large opening diameter, angled type etc.)
and specification conditions (high temperatures etc.) with which a valve is not.
– A valve is a standard (mass-produced) part, while dampers are custom designed and manufactured,
and so it is possible to serve the customer’s needs in a flexible manner.
