NPT THERMOSTATIC RADIATOR VALVE BODIES
FTnBSion
The control mechanism of the
thermostatic radiator valve is a
proportional temperature controller,
composed of a liquid fi lled bellows.
With increasing temperature the
liguid expands which, in turn, causes
the bellows to expand. When the
temperature decreases the opposite
occurs; the bellows contracts allowing
the spring to return it to the original
position. By connection to the valve
stem, these movements adjust the heat
transfer medium to the radiator.

½ and ¾" tail pieces.

*eX EeaSTres
The thermostatic control head is fi lled
with a non compressible liquid bellows
(1). Plus, the radiator valve body has extra
strong valve stem compression spring (2).
The non compressible liquid provides the
force required to compress the strong
valve stem spring. When the temperature
decreases, the liquid bellows contracts,
which allows the valve stem spring to lift
the valve plug from valve seat after long
periods of non movement. This ensures
that after a long ‘off-season’, when the
actuator operates for the fi rst time, the
spring reliably lifts the valve plug off the
seat without sticking. In addition, the
200000 control head features an easy-
to-use locking mechanism that prevents
unauthorized temperature set point
changes and a range stop adjustment
that limits the maximum temperature
setting to save energy and over-heating.

The Caleffi thermostatic control
heads 200000 and 201000, and
the radiator valve bodies 220 and
221 series in combination with
control heads 200 and 201 are
approved to EN 215 (KEYMARK) and
Thermostatic Effi ciency Label (TELL):
Level A, Reg. 10428/9-20110527.
Under EN 215 these devices are
certifi ed to meet manufacturer
quality assurance requirements with
reference to temperature setting
and adjustment, nominal fl ow rate,
hysteresis, and leak tightness of the
body assembly and stem seal. The
European TELL certifi cation promotes
responsible energy usage and
provides information to customers
when selecting products. The control
heads 200 and 201 are “A” rated
for effi ciency. Additional information
available on request.
