Although existing check-valves has control one-directional fluid flow function, but positive flow of fluid resistance is larger.In conveying
In the pump and pipe-line system of all kinds of media, in order to prevent medium from flowing backwards, check-valves typically can be all installed.For check-valves product
For design manufacturer, typically all can focusing on valve and reliably can close when medium flows backwards and valve energy concern
Seal request needed for no satisfaction, and valve drag characteristic operationally is then more ignored.Backflow preventer normal work
During, check-valves unlatching is produced to be even more important to the pressure loss that system media brings, and pump and pipe-line system institute are supporting
If check-valves with low flow resistance characteristic, can undoubtedly reduce the crushing of system, so as to reach reduce energy consumption, reduce produce into
This purpose.
