The POWERTROL family solves the versatile and increasing requirements for steam conditioning and cooling with a flexible design principle and maximum efficiency. Our modular system and its variety of products offers the right concept for every steam cooling application. Starting with the classic seat or stem injection up to the high-tech steam assisted nozzle. The more flexible mode of operation of modern power plants, with increasing demands on temperatures, pressures and further developments in power plant technology, is answered by the continuous expansion of the performance of our trims and valve housings of the steam-conditioning stations. The perforated cages are calculated and executed according to the flow conditions as well as the required noise level and rangeability. The housing of our valves in the field of steam conditioning is modelled and manufactured according to the latest state of the art and production processes – this way, the high-performance solutions always meet all requirements for higher temperature gradients during start-up and for the service life due to thermal fatigue. For safety applications, a dirt strainer is connected upstream in the steam inlet. This prevents the ingress of foreign particles and protects against defects. POWERTROL stands for maximum control performance in steam conditioning with unique service and maintenance convenience.
