Radiator Thermostats for Domestic 2-Pipe
System RAS-D Range
Application
RAS-D built-in
sensor
RAS-D radiator thermostats are designed for use
in 2-pipe domestic heating systems.
All RAS-D Combi Packs comprises either a RA-FS
angled pattern bi-directional valve or a RA-FN
straight valve and a RAS-D sensor designed for 2pipe heating systems. Combi Packs are also
available with a RLV-D lockshield valve. For
further data on the lockshield valve please see
separate RLV-D data sheet.
The RA-FS have a ½” BSP (R½”) tail piece
connection to the radiator and are available with
15mm, 10mm or 8mm compression fitting or an
elbow with 10mm push-fit fitting to connect the
valve to the pipe work.
The RA-FS valve bodies are reversible and bidirectional and include a flow-selectable feature
to ensure trouble free installation without any
risk of water hammer. For optimum performance,
Danfoss recommend the sensor be mounted
horizontal where at all possible.

The straight RA-FN have a ½” BSP (R½”) tail piece
connection to the radiator and is available with
15mm compression fitting is not bi-directional.
All valves are supplied with a protective cap,
which can be used for manual regulation during
the construction phase. The cap must not be
used as a manual shut of device.
RAS-D sensors are equipped with a snap-lock
mechanism, which ensures a quick, firm
mounting to the valve without the need of tools.
Both built-in and remote sensors are available in
the RAS-D range. RAS-D incorporate a “Frost
Protection” setting and a “Positive Off” feature for
maximum user flexibility. Temperature range is
from 8°C to 28°C.

Valve bodies are manufactured from brass with nickel
plating. The spindle in the gland seal is of chrominium
steel and works in a lifetime lubricated o-ring. The
complete gland assembly can be replaced without
draining down the system.
