A pressure vent valve for ventilation of the interior of a motor vehicle, with a frame with at least one sealing surface and with at least one flexible valve flap mounted on the frame. In an idle position, the valve flap assembly abuts the sealing surface to prevent airflow through the pressure vent valve. When a sufficient pressure occurs, the valve flap assembly assumes an open position lifted from the sealing surface to allow airflow through the pressure vent valve. The pressure vent valve further includes an installation indicator formed in or on the frame to ensure alignment during installation.
