Hi Phil,
The standard Maxflow valve has a 'plain' dip tube that reaches the bottom of the bottle, for bottles that are mounted with the valve at the top.
The Race valves have a short dip tube with a billet alloy trumpet fitted to the end. The short tube is to enable the bottle to be mounted with the valve downwards and the trumpet prevents disruptive turbulence at the entry. The combined result is more dense and enhanced flow, plus it removes the need to purge the hose if the rest of the components are fitted appropriately.
We also offer a version that has a long dip tube with the addition of a trumpet but inverting the bottle and using a short tube is the best option
