More Information
Summary:A discharge valve for a pressurized container is provided with a telescoped axially movable tubular nozzle which cooperates with a sidewall aperture in a stationary elastomeric encircling sleeve for controlling the egress of material. A valve stem within the nozzle cooperates with a discharge orifice at the outer nozzle end to seal same when the nozzle is in valve closing position and to expose same when the nozzle is moved to valve open position thereby preventing nozzle clogging.
