5. A method of controlling fluid flow comprising:
providing fluid to an inlet passage that is in communication with a valve chamber;
positioning a valve member in a first axial position in the valve chamber where fluid flow between the inlet passage and the valve chamber is blocked, fluid flow between the outlet passage and the valve chamber is blocked, and fluid flow between the vent passage and the valve chamber is open regardless of a rotational orientation of the valve member in the valve chamber;
positioning the valve member in a second axial position in the valve chamber where fluid flow between the inlet passage and the valve chamber is open, fluid flow between the outlet passage and the valve chamber is open, and fluid flow between the vent passage and the valve chamber is blocked regardless of the rotational orientation of the valve member in the valve chamber.
