Old “Modul” radiant manifold

rwhtgrwhtg Posts: 26Member
Has anyone seen these, worked on, or have any literature on balancing?? My internet searches have not been helpful. Possible owned by watts now? Also does “cazzinagia” mean anything to anyone?? This install was late 90’s early 2000’s

    This looks similar to a style I worked on before. If you remove the brass caps on the manifold without the zone valves does a allen wrench fit in it? Because if it does then that is how you balance the manifold. At least on many manifolds similar that is.

    Yes that is a company that Watts now owns. I think John is correct that you will find an allen under the upper cap.

    You can buy inline flowmeters to add if you want to know actual flow rates.

    Where are some of their current valves with that logo.
