Thermostatic radiator valves

for towel warmer style radiators

338–343, 200 series

01009/13 NA

Function

Convertible radiator valves are typically used in North America for

controlling the ﬂuid to towel warmer style radiators. These special valves

can be converted from manual to thermostatic operation by simple

replacement of the adjusting knob with a thermostatic control head.

This means that the ambient temperature of any room in which they are

installed can be constantly maintained at the set value.

These valves have a special tailpiece with rubber hydraulic seal,

permitting quick, safe connection to the radiator without the use of

additional sealing materials.

The radiator isolation and balancing valves have a removal protective

cap, when removed exposes the allen head screw for adjusting the valve

plug position.

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