    Great idea, and it works!

    Looks like a good idea and I've always liked Delavan but the "C" & "D" illustration on their site is showing a pretty
    large stream of after drip. I'd tend to look for a very bad
    pump PRV with that much oil coming out at shut down. Little more than a 20% drop in that photo.

    standard nozzles can't prevent the after drip shown in the photos.(E&F) I wouldn't turn to a nozzle to correct that level of after drip. I've seen some clean cut off with standard nozzles.

    Wonder how long they will last before the spring breaks? I have never used them. Anyone have any track record on these?
    I know a number of places I would love to install these instead of oil delay vlvs.

    Agree that the pictures are not the best comparision. Must be one old worn out pump cut-off, and maybe a little head pressure from the fuel tank?

    It's not to replace an

    oil valve, but rather to work in conjunction with one, no leaks, positive cutoff, that's the goal!

    pressure on nozzle

    oil valve and check at nozzle?hmmmm doesn't that create a closed loop that may increase in pressure with heat?just wondering aloud, I'll have to try some experimenting with my burner.
