Diverter Valves:
Straight (part number 1016311) and angled (part number
1016312) diverter valves are available for use in a one-pipe
system (fi g. 4). Shut off s 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 % fl ow through the
radiator and 65% through the bypass. Other fl ow
percentages are easily set according to the diagram (fi 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 fi ttings now connect
to the diverter valve.
2. Allow 5” fl oor clearance below the radiator for the
straight; 4” for the angled diverter valve.
