A container filling machine filling valve arrangement for use in filling machines for filling containers, such as bottles, cans, or similar containers, with a liquid. The valve arrangement comprises a valve and an always-open gas cutoff element. The valve controls the flow of liquid from a liquid source into a container to be filled. The gas cutoff element is configured to: permit flow of liquid through the gas cutoff element, prevent or minimize gas from flowing through the gas cutoff element, and generate a swirling of liquid flowing through the gas cutoff element. The gas cutoff element is a substantially flat, planar element.
