Abstract: A valve, particularly useful in a fire extinguisher, which utilizes a stem movable in a passageway having a head connected to the stem. The head includes a relatively hard member possessing a hard outer surface which fits snugly within the passageway. The head further includes a deformable portion adjacent the relatively hard surface of the relatively hard member. The relatively hard surface of the relatively hard portion contacts and scrapes the wall portion prior to sealing which is effected between the deformable portion and the wall of the passageway.
