IVC Check / Non Return / Reflux Valves

The choice of a check valve for pumping  is always ticklish for a system designer. Quantum of head loss vs. non slam characterstics, quick closing vs. dampened slow closure , vertical vs. horizontal application, spring assisted vs. self closing door, maintenance free long life at a relatively higher price vs. low price maintenance prone, are but a few parameters considered vis-à-vis application. We can help select the right valve that will be good value for money.
