Abstract:  
I have been asked, "What's the reason for the success of the MagnaValve?" There is no question that this magnetic valve, with no moving parts, has captured the attention of the shot flow market for the last 20 years. Some people still marvel that the valve works at all; that it actually functions as a "Normally Closed Valve" and stops the flow and weight of steel shot when it's not energized.
