Diverter Valves:
Straight (part number 1016311) and angled (part number
1016312) diverter valves are available from Buderus for
use in a one-pipe system (g. 4). Shut offs are located on
the supply and return branches to the radiator, allowing to
isolate the radiator from the piping system so it can be
drained and removed without decommissioning the
complete heating system.
Each diverter valve is factory set for 35 % ow through
the radiator and 65% through the bypass. Other ow
percentages are easily set according to the diagram (g.
5). To adjust the bypass, turn the spindle clockwise to the
fully closed position. Then open the bypass spindle the
desired number of turns from the fully closed position.
Refer to the chart that is on page 30, explaining the
pressure drop for a one-pipe system with diverter valves.
You will need to add up the pressure drop of radiator and
diverter valve when sizing the circulator.

Installation considerations:
1. The valve mounts directly to the supply and return
of the radiator. The compression ttings now
connect to the diverter valve.
2. Allow 5” oor clearance below the radiator for the
straight; 4” for the angled diverter valve.
