Barberi coplanar distribution manifolds allow the installation of distribution and regulating groups in heating systems, connecting them to the heat generator or buffer storage. All models are equipped with secondary connections with running nut with centre distances between the outlets common to most of the groups on the market: 90 mm for DN 20, 125 mm for DN 25 and DN 32. They allow quick installation in reduced spaces, thanks to the internal conformation of the flow and return chambers. The P72.DN20, P72.DN25, P72.DN32 models are called “UP” manifolds as they have the secondary connections for the groups on the upper side and the main connections for the boiler on the lower side. The P74.DN20 and P74 models are manifolds with hydraulic separator integrated in the lower part. They have the secondary connections for the groups on the upper side, the main connections for the boiler on the lower side and Rp 1/2 connections for any test port. The V34.DN25 model is an “UP/DOWN” manifold as it has the secondary connections for the groups on both sides and the main connections for the boiler on the lower side. The manifolds are made of painted steel and are equipped with insulation against heat loss. The supplied brackets allow all models to be installed even upside down.
