In this paper, a creation and a validation of the pressure loss model for the specific and widely used design of the steam turbine inlet control valve assembly called an L-valve is described. This model is based on a wide range of experimental measurements on the valve model installed in an air tunnel and it is validated by numerical simulations using the commercial code. The results of experimental measurements as well as numerical simulations are shown. Furthermore, differences between experimental and numerical results are discussed. According to the results, the pressure loss model in the form of a smart and effective procedure for calculating the valve assembly pressure losses and choosing an optimal valve sizes has been created.
