Non-Reopening Check Valves

What is a non-reopening check valve? This element is a modeling convention, as opposed to an item that can be ordered from a manufacturer, because by definition a check valve is designed to open and close in response to flow and pressure conditions. The way Pipe2016 models an “ordinary” check valve is by allowing it to open when the differential …

Device – Dynamic Air Valve

After activation, the Dynamic Air Valves continue to allow water (not just air) to flow out after all air is vented. The valve is gradually closed to reduce water column velocity in a highly controlled manner eliminating the air slam pressures.
