    Abstract: An apparatus for forming plastic preforms into plastic containers, includes at least one forming station which forms the plastic preforms into the plastic containers by applying a flowable medium to the plastic preforms, wherein the forming station includes a blow mold, and a rod-like body which is insertable into the plastic preforms via a mouth of the plastic preforms, and a moving device which is configured for moving the rod-like body in the longitudinal direction of the plastic performs. The rod-like body has a channel for guiding the flowable medium, and the forming station has a valve device controlling the supply of the flowable medium into the channel. The valve device is arranged on the moving device and/or a ratio between an inner diameter of the rod-like body and an outer diameter of said rod-like body is, at least in sections, smaller than or equal to 0.5.
