Intensive vibration of inlet piping system was discovered during test period of 1000 MW SKODA turbine operating with inlet-saturated steam. Unwanted oscillations of the piping system required new view on construction of control parts of the turbine. Intensive research of valve models took place, numerical simulation were done. The original alternative of the valve with shaped plug was compared with the valve characterized by flat-bottom-plug and a muffler.
