DK - Desuperheater

Series DK atomizing valves are used to control the temperature of superheated steam (or gas). The desuperheater type DK is designed so that even at low injection water quantities an efficient spray of very fine droplets (mist) is obtained. The nozzles in the sprayhead are designed to give the injection water a high velocity and a radial rotating movement under all conditions. The result
is a fine pressure atomization and very quick evaporation.

The main feature of the DK desuperheater is Excellent atomizing characteristics at a delta p water/steam of 5 bar (72.5 psi) and at steam velocity of 10 m/s possible. The field of application starts at steam velocities of 5 m/s and a rate of overheating to the saturation of 3°C. More favorable conditions will improve the effectiveness of the desuperheater.
