ABSTRACT An air control valve is provided for use in a spa to regulate the flow of air to a hydrotherapy jet in which a recessed control knob is accessible at a rim of the spa to actuate a movable valve member to selectively constrict or dilate an air flow passage through the valve body which has an air intake opening underneath the spa rim to isolate the noise associated with the intake opening from the user.
