A vent valve may include, among other things, a valve body having an inlet opening and an outlet opening forming a flow path. The inlet opening may be oriented in a first direction and the outlet opening may be oriented in a second direction. A poppet member may be provided on or about the valve body and can be configured for movement between an opened position and a closed position relative to the inlet opening. The poppet member may be movable along the valve body in a direction that is perpendicular to the first direction of the inlet opening. A float member may be attached or operatively connected to the poppet member, the float member configured to move the poppet member between the first and second positions.
