Abstract
A fully recyclable valve housing for engagement with a neck of a container, such as a beer keg, has an inner port for liquid and a concentric outer port for pressurized gas, with openings for admitting pressurized gas into the container. A dip tube is connected to a bottom end fitting, communicating with a valve stem within the valve housing. A valve member controls flow through the concentric ports, and a spring element located about the valve stem urges the valve member upwards to close the ports. The spring element is molded from a resilient polymeric material and comprises a plurality of C-shaped sections angularly arranged in two interconnected stacks on opposite sides of the valve stem such that movement of the valve member causes concurrent resilient deformation of all the sections.
