AKO Temperature Regulator selfactuated
4. Operating principles
AKO Thermostats are equipped with interior, easily exchangeable thermostats which
register the temperature of the medium surrounding them at the measuring point (point of
installation) and convert it into another physical dimension, namely extension and therefore
into a change in distance or length (the valve stroke). With increasing temperature and
exceeding the opening start temperature, the tubular slider is lifted off the seat of the valve
and opens the path from A to C, at the same time and in the same ratio the path from A to B
is closed. The change in path occurs proportionally to the change in temperature of the
medium flowing through. The descriptions A, B and C have been cast on the housing of the
thermostat. The thermostats can be installed in every position.
