I would like to dispense .3-.5 ml/stroke from a 500ml. canister in the inverted position. There is no vent into the canister so air must be returned by the valve.
I've been using a finger pump like the ones found in hairspray but they leak when inverted. To add a little more difficulty; these valves will be placed into a dispoable product so they have to be inexpensive. What would be the name of this valve? Also, if necessary could a valve like be made?
