A dispenser for use with a pressurizable fluid container. The dispenser comprises a head removably connectable with the container. The head includes an inlet, an outlet, a valve seat, a cavity and a chamber for fluid communication between the inlet and outlet. The valve seat is located between the inlet and the chamber. The cavity is located between the inlet and the valve seat. A valve body has a portion locatable in the chamber. The valve body is actuatable for movement between an open position allowing fluid flow through the chamber and a closed position blocking fluid flow through the chamber. The valve body includes a seal seat surface adapted to face in a direction towards the inlet when the valve body is within the chamber. A seal is receivable on the valve body for engagement with the seal seat surface. The seal is engageable with the valve seat to define the closed position. A cap member is engageable with a surfaced defining the cavity in the head to fixedly attach the cap member within the cavity. A bias mechanism is engageable with the cap member for normally biasing the seal towards the valve seat.
