ABSTRACT:
A foam dispensing gun is provided which dispenses a urethane foam. The foam gun, in one aspect, has a dual valve member in which valve seats are moved relative to valve members to open and close flow paths through the foam gun. The valve member opens the flow paths substantially simultaneously and to substantially the same degree so that the A and B resins will be mixed in a 1:1 ratio. The gun is provided with a locking or stop mechanism to prevent accidental activation of the foam gun. In a second aspect of the invention, a disposable urethane foam gun is provided which has only one moving part and no O-rings.
