A fuel vapor control valve for controlling the flow of fuel vapor and liquid fuel through an aperture in a fuel tank is provided. The fuel vapor control valve includes a housing mounted in the aperture and formed to include an inlet and an outlet, a chamber disposed in the housing, a pressure-relief valve disposed in the camber, and a vacuum valve disposed in the chamber and formed for movement relative to the pressure-relief valve. The vacuum valve is biased to relieve subatmospheric tank pressure below a predetermined minimum pressure and includes a base that is mounted on the pressure-relief valve and arranged to define a venting aperture. In addition, the fuel vapor control valve includes a ball that is movably positioned in the chamber to selectively interrupt the flow of fuel vapor through the venting aperture.
