1) Capacity of manifold assembly. Bypass through radiator: 35%.
2) The maximum differential pressure specified is the maximum pressure at which the valves give satisfactory
regulation. As with any device which imposes a pressure drop in the system, noise may occur under certain
flow/pressure conditions. To ensure quiet operation, maximum pressure drop should not exceed 30 to 35 kPa.
The differential pressure can be reduced by using Danfoss differential pressure regulators.
3) Includes compression fittings for connection pipe

The manifold assemblies RA-KE and
RA-KEW are versatile control units for all
types of radiators with standard ½” side
connections. RA-KE and RA-KEW valves
are for 1-pipe pumped systems.
The manifold assembly includes a
manifold valve body with shut off
facility, a connection pipe and a radiator
valve body.
The centre distance between
connection pipe is 35mm, which allows
system pipes to be connected using a
junction box.
Danfoss manifold assemblies can be
used with all RA2000 sensors.
A wide range of compression fittings
for steel, copper, PEX and AluPex piping
allows fast and flexible installation. See
page 20.
To avoid deposits and corrosion the
water quality should comply to VDI
2035 guidelines
