A valve in which a small driving force of a drive source is required when the valve is closed. A valve includes a valve housing and a valve body to be driven by a drive source, and controls a flow rate of a fluid flowing through a through-flow passage in a direction opposite a closing direction of the valve body, by moving the valve body from a control region to a closing region. The valve body has an effective pressure-receiving area where a pressure of the fluid acts on the valve body. The effective pressure-receiving area is switched between the effective pressure-receiving area in the control region and the effective pressure-receiving area in the closing region. The effective pressure-receiving area is smaller than the effective pressure-receiving area.
