The DZE series presented here is used for highest pressures and temperatures. Turbine Bypass Valves are used in all industries where high pressure steam has to be converted to a lower pressure and at the same time to be cooled down. By the design of one or more levels a built-in choke and a patented integrated spray water injection is reducing the vapor pressure and the temperature according to the specified operating parameters. Both tasks are performed without installing a cooler at the outlet of the Steam Conditioning Valve. The patented ring shaped spraywater injection is placed in the low pressure area. Its use is therefore of particular interest for power generation, steam distribution networks of the chemical industry and paper and sugar factories.

A compact hydraulic drive allows shortest reaction time (less 1 sec) to design flexible operating processes. The materials are choosen according to the specific requirements to guarantee an operating of modern baseload power plants as well as the extreme characteristics of peak-load electrical power plants.
