Abstract of the Disclosure A tiltable discharge valve for pressurized containers is suitable for dispensing a high viscosity product, at an unexpectedly low pressure. The valve provides for increasing flow-through cross-sectional area, as the container pressure falls, and includes a large disc or head secured to a tiltable stem. The container pressure presses the disc into the valve seat and the valve disc tilts around its fulcruming ring to raise its sealing ring off the valve seat. The valve seat is quite yieldable and the sealing ring sinks in deeper into the seat under higher container pressure and sinks less deeply into the seat as the container pressure decreases, whereby the extent the sealing ring rises off the seat upon tilting of the stem is container pressure determined, and the amount of product delivered to the stem outlets remains generally constant even as container pressure decreases.
