Application
RA-IN/HC-RE radiator valve
All RA-IN/HC-RE valve bodies can be used
together with all types of thermostatic elements
with Danfoss RA connection in two-pipe heating
systems.
RA-IN/HC-RE valves are fitted with a kv limiting
device for presetting of max. water flow within a
range of 0.052 to 0.84 m3/h.
The valve bodies are supplied with a protective
cap which can be used for manual regulation
during the construction phase. The protective
cap must not be used as a manual shut off device.
A special manual shut off device (code no.
013G5002) should be used. To be able to
distinguish between other valve bodies of the RA
2000 series the RA-IN/HC-RE protective cap is
white.
RA-IN/HC-RE has a connection for PEX 12 x 1.1
mm and 16 x 1.5 mm hydro cable, both axial and
radial compression fittings are available. RA-IN/
HC-RE are also available with 1/2” conection.
Valve bodies are manufactured from brass with
nickel plating. The pressure pin of 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.
RLV-S/HC lockshield valve
RLV-S/HC-RE is intended for mounting on the
outlet of the radiator.
Using RLV-S/HC-RE each radiator can be shut off
individually to allow trouble-free maintenance or
repair without affecting other radiators in the
system.
RLV-S/HC-RE is available in angle version with a
connection for PEX 12 x 1.1 mm and 16 x 1.5 mm
hydro cable, both axial and radial compression
fittings are available.
RLV-S/HC-RE is also available with 1/2”
connection.
Default setting is fully open valve.
Dimensions correspond to DIN 3842-1.
In order to avoid deposition and corrosion the
composition of the hot water must be in
accordance with the VDI 2035 guideline (Verein
Deutscher Ingenieure).
Should water treatment be used it is essential
that dosing instructions of the manufacturer are
strictly observed. It is recommended that
formulations containing mineral oil are avoided.
Approved to EN 215
Danfoss RA-IN valves are manufactured to the highest standards, and are approved to the European
Standard EN 215.

Principles
Closing and Opening RLV-S/HC-RE
Use an 8 mm Allen key to close the RLV-S/HC-RE
by turning it clockwise.
Open the RLV-S/HC-RE by turning the Allen key
anti-clockwise. With 4 turns the valve will be fully
open.

1)
The kv-value indicates the water flow (Q) in m3/h at a pressure drop (∆p) across the valve of 1 bar; kv = Q: √∆p. The kv-value is stated according to EN 215, at XP
= 2K, i.e. the valve is closed at 2°C higher room temperature. At lower settings the XP value is reduced to 0.5K. The kvs-value states the flow Q at a maximum
lift, i.e. at fully open valve.
2)
Kvs-value for RLV-S/HC: 1.26 m3/h
3)
Working pressure = static + differential pressure. The maximum differential pressure specified is the maximum pressure at which the valves give satisfactor y
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 the use of the Danfoss differential pressure
regulators.
