I'm replacing the gas manifold in my small 2-keg keezer (actually a converged fridge) with a duotight manifold with the mini inline regulators from Kegland. I'm planning to install duotight ball valves in order to isolate each keg if need be. Is there any advantage to placing these ball valves on the input sides of the regulators or the output sides? I've seen pictures online for both configurations.
