How to size a valve
WebValve Sizing Technical Bulletin Scope Valve size often is described by the nominal size of the end connections, but a more important measure is the flow that the valve can provide. … WebDec 17, 2011 · In this application, the opening of the check valve is delayed with a timer until the air release valve can discharge the air in the pump column to achieve a controlled 1-ft/sec to 2-ft/sec (0.3-m/sec to 0.6-m/sec) flow velocity in the pump column. For a 20-ft (6-m) lift, the delay time will be about 10 to 20 seconds.
