Thermostatic radiator valves

for NPT threaded radiators

220 series

01034/13 NA

Function

Thermostatic valves are typically used for controlling the ﬂuid ﬂow to the

radiators of hydronic heating systems. They are composed of two parts:

a control head and valve body.

The control contains a liquid-ﬁlled thermostatic element that automatically

controls the opening of the valve to maintain room temperature at the

set value. This prevents unwanted room temperature rises, providing

considerable energy savings.

The valve body has NPT threaded connections: female threads to

connect to the system and union male threads to connect to the radiator.

These valves can also be used for isolating and balancing.

Principle of Operation Valve closed The thermostatic control head is a proportional temperature controller, containing a liquid-filled bellows thermostatic sensor. 2 The valve plug is normally in the (1) springto-open (normally open) position without the control head, or when the control head is in the maximum open position (setting 5).

Installation Remote sensor control Thermostatic control heads should be installed in the horizontal position. Refer to the dimensions shown to properly install the thermostatic control head with remote sensor, code 203502. CALEFFI CALEFFI 60" CALEFFI 4" The sensitive element of the thermostatic control head must not be installed in niches, alcoves, behind curtains or directly exposed to sunlight, any of which would sense incorrect temperature values.
