A device for distributing and dosing pasty, liquid, semi-liquid or pulverulent products comprises a valve body which is provided with a through channel for moving the product from a feed opening to a delivery nozzle in dosed quantities. A valve seat is formed in the channel and a valve is mounted in the channel. The product through channel comprises a rectilinear product, passage segment in which the valve seat is disposed and in which the valve and the valve rod extend axially and in full. Moreover, the valve drive mechanism penetrates the product passage segment at least in part. The drive mechanism is in contact with the product such that the mechanical link between the valve rod and the drive mechanism is also in contact with the product and is lubricated by the product.
