Re: Float Valve Curiosity - New v. Old

The biggest issue I have seen with the flat elastomer cushion designs is they eventually compress and form a round circle where the seat presses into the soft surface. Daytona says the design eliminates the slow leak caused by worn needle valves but depending on how resilient and thick the elastomer substance is it may eventually harden and no longer compress to the point a slow leak develops. I honestly do not know if it is an issue with the Daytona seats and gasoline but it was an all too frequent issue on some air solenoid valves that were used in equipment I serviced. I also found the flat seat an issue with the solenoid valve that turns the vacuum supply to my 47 Electromatic clutch valve on and off. That rubber seat had gotten hard and with the round circle depression unable to compress it could no longer seal at all.
