The temperature control angle disc valves DN 20-65 of type 24с are intended for the steam temperature control.
They are used for the control of steam superheating temperature on boilers, reduced steam temperature in DS, PRDS, FRPRDS of power generating units and other pipelines, as well as on continuous blowdown pipelines.
