ABSTRACT OF THE DISCLOSURE A method and system for filling and for seal- ing valve bags of the type having a water activated seal- ing means on the interior of the filling valve. A fill spout or nozzle is provided to maintain the filling valve free from contamination by the material being dispensed into the bag. The nozzle has an air conduit that sup- plies air to a location adjacent the water activated sealing means during the filling operation and a water spray conduit that supplies a water spray to activate the sealing means at completion of the filling operation. A suction source is connected to the material supply passage of the nozzle and is actuated momentarily while the noz- zle is being removed from the filling valve and prior to the end of the filling valve entering the water activated region of the valve in order to prevent material from fal- ling from the end of the nozzle onto the activated por- tion of the sealing means. A sealing nozzle separate from the filling nozzle is also disclosed. -1-
