A container of pressurized product in combination with a delivery apparatus, comprising:

• an actuating element carried by the delivery apparatus;
• a valve carried by the container and including a valve element actuable to open the valve wherein the valve element includes a circumferential side wall having an interior surface defining a circular cross-section first channel passing axially through the valve element, an exterior surface, and a tip surface;
• a second channel extending radially from the interior surface into the sidewall of the valve element, the second channel not extending fully through the sidewall and exiting through the tip surface of the valve element;
• wherein the actuating element has a tapered end with a circular sealing surface on the tapered end that obstructs the first channel when brought into engagement with the valve element, but which does not fully obstruct the second channel.
