Description
DTCV - control valve for temperature differential control
When a heat exchange system operates under saturated conditions, an increase in flow rate will not correspond to an increase in heating or cooling capacity. The carrier fluid is no longer able to release the energy, therefore there will be a reduction in the temperature difference (ΔT) between inlet and outlet.
The use of the DTCV control valve makes it possible to keep the ΔT constant, at a set value, between flow and return by acting on the flow rate of the carrier flow: if the ΔT tends to decrease the flow rate will be decreased, if the ΔT tends to increase the flow rate will be increased.
