Panel Radiators - Fitch Specialties

Applications manual
Diverter Valves:
Straight (part number 1016311) and angled (part number
1016312) diverter valves are available from Buderus for
use in a one pipe system (fi g. 6). Shut offs are located on
the supply and return branches to the radiator, isolating
the radiator from the piping system. This will enable you
to remove the radiator after draining it to do any
maintenance needed to the wall behind it.
Each diverter valve is factory set for 35 % fl ow through
the radiator and 65% through the bypass. Other fl ow
percentages are easily set according to the diagram (fi g.
7). 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, It explains the
pressure drop for a one pipe system with diverter valves
for detailed pressure drop information when using
diverter valves in one pipe systems. You will need to add
pressure drop of radiator and diverter valve together
when sizing circulator

Installation considerations:
1. The valve mounts directly to the supply and return
of the radiator. The compression fi ttings will now
connect to the diverter valve connections.
2. Allow 5” fl oor clearance below the radiator for the
straight; 4” for the angled diverter valve.
3. Due to its projection towards the mounting wall, the
angle diverter valve cannot be used on the model
#11 radiators unless a small recess is cut into the
wall.
