PRODUCT DATA
Application
Thermostatic radiator valve bodies (TRV bodies) are fitted on
the supply or return of radiators or heat exchangers. Together
with a radiator thermostat, for example the Thera-4, they
control the room temperature by regulating the flow of hot water
into the radiator. The temperature of different rooms is
controlled individually and energy is saved.
TRV bodies of this type have quiet operation and are fitted to
the supply of radiators on two-pipe systems with low, medium
or high flow rates.
The valve insert can be replaced while the system is running
and without draining using the service tool (see ‘Accessories’).
TRV bodies of this type are suitable for
• Honeywell radiator thermostats with M30 x 1.5 connection
• Certain Honeywell MT4 actuators
• Honeywell Hometronic HR80 and Roomtronic HR40 actuators

valve insert can be replaced by any other AT-Concept valve
insert, i.e. BB, KV, UBG, SL, VS, FS, FV and SC.

Materials
• Angle/straight to DIN: valve housing made of nickel-plated
red bronze
• Corner angle, horizontal angle and swanneck tailpiece: valve
housing made of nickel-plated hot-forged brass
• Valve insert made of brass with EPDM O-rings and soft seals
and stainless steel spindel
• Protection cap made of red, blue or green plastic
• Union-nut and tailpiece made of brass, union-nut nickelplated, tailpiece optionally nickel-plated
Please Note:
• To avoid stone deposit and corrosion the composition of the
medium should conform with VDI-Guideline 2035
• Additives have to be suitable for EPDM sealings
• System has to be flushed thoroughly before initial operation
with all valves fully open
• Any complaints or costs resulting from non-compliance with
above rules will not be accepted by Honeywell
• Please contact us if you should have any special requirements or needs

Function
Thermostatic radiator valves enable individual control of room
temperature and thus save energy.
The TRV body is controlled by the radiator thermostat. Air from
the room passing over the sensor of the radiator thermostat
causes the sensor to expand when the temperature rises. The
sensor acts onto the valve spindle and this causes the TRV
body to close. When the temperature falls the sensor contracts
and the spring-loaded valve spindle is opened. The TRV opens
in proportion to the temperature of the sensor. Only the amount
of water required to maintain the room temperature set on the
radiator thermostat can flow into the radiator.

Design Example
Given: Flow rate 150 kg/h
Required: Pressure loss (∆p) with a P-band of 2K
Solution: The required pressure loss for the K5 valve disc is found at the intersection of the flow line
with the line for the chosen valve performance P=2K
Result: ∆p = 62 mbar = 6 200 Pa
