Design
The thermostatic radiator valve body consists of:
• Valve housing PN10, DN15, 20 or 25 with
• internal thread to DIN2999 (ISO7) on inlet and external
thread for union-nut with radiator tailpiece on outlet. Inlet
suitable for threaded pipe, DN15 and 20 also suitable for
copper and precision steel pipe using compression fittings
(see ‘Accessories’)
• external thread connection to DIN/ISO228 with union-nut
and radiator tailpiece on outlet
• Valve insert
• Protection cap
• Union-nut and radiator tailpiece

H type TRV Body
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 or heat exchanger. The temperature of different rooms is controlled individually and energy is saved.
Thermostatic radiator valves of this type have quiet operation
and are fitted to radiators on two-pipe systems with large flow
rates or radiators in one-pipe systems.
The flow rate can be preset according to system requirements.
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
Features
• For heating-systems with high water flow rates
• Available for installation on the supply or, with horizontal angle body, on the return
• Reverse flow possible - note lower max. differential pressure
• Standard M30 x 1.5 thermostat connection
• Quiet operation
• Valve insert can be replaced while system is operating
and without draining the system
• Valve opening spring is not in the water
• With white protection cap
Materials
• Valve housing made of red bronze
• Valve insert made of brass with EPDM O-rings and seat
sealing
• Spindle made of stainless steel
• Protection cap made of white plastic
• Union-nut and tailpiece made of brass

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.
• 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
