The low pressure side of the reducing valve (9) is directly connected to a gas channel (3a) in the housing of the beer tap (3), said gas channel communicating with the interior of the keg. The reducing valve (9) is a needle/cone valve, where the valve body is controlled by a bellows device (30) arranged in the housing of the valve and including a closed control gas mixture (21) which at least includes carbon dioxide.</p> |
