AKO temperature regulators of the illustrated series are suitable for keeping medium temperatures (eg water, oils, etc.) constant and can be used both as divider and as a mixing valve. They are characterized by a high degree of maintenance-free operation, exceptional serviceability and robustness. An exchange of the internal parts is possible – without removal of the control valve from the pipeline – on the spot. Incorrect assembly can be excluded. The temperature regulators can be used in any position.


The AKO 3-way temperature control valve with internal thermostats has, depending on the nominal width, a number of expansion elements, each equipped with its own slider. The strain elements are surrounded by the medium and absorb the temperature of the medium. The characteristic of the regulator is determined by the opening start and the full opening temperature of the expansion element. When the delivery medium reaches the opening temperature of the expansion element, this opens the one path of the three-way controller while the other path begins to close.
