For the modern steam generator feed water flow control systems and new generation products requirements for vibrating characteristics and hydrodynamic noise are significantly increased. Currently, control devices meet the requirements of regulatory documents on vibration noise characteristics developed in 1980-ies. To solve the problem of compliance with modern requirements previously flat (two dimensional – 2D) statement of problem was widely used. This approach does not give a complete and adequate picture of the physical fields of electro-hydraulic equipment. Therefore, it is necessary to gradually complicate the task and goes into a three-dimensional area. We have done joint work with a number of computational companies that distribute or produce the various types of code for computational fluid dynamics (CFD) in order to determine ways of improving the acoustic quality of our products by the means of three-dimensional mathematical modeling with obtaining physical field parameters. On the basis of received information we made out the subsequent verification of experimental studies of the valve model, which had been previously analyzed in CFD, at the test bench.
