摘要： The invention relates to any aerosol valve system having a principal product flow valve and a ball valve shut-off valve disposed in the product flow path which terminates through the product flow path during unacceptable orientation of the aerosol container and a mechanism for equalizing the pressure on each side of the ball valve such that the ball will promptly dislodge from its valve seat and return to its unseated position upon closing of the principal valve and the return of the aerosol container to an acceptable orientation.
