Some experimental research work has been presented as to the irnpact of the anti-vortical grids upon flowing process within exhaust manifolds and control valves of the steam turbines. The effect of the anti-vortical grids on any explored items being vibrated has been considered along with some relevant values of the pressure pulsation within a walve and pipeline furthermore. A significant reduction of this pulsation under grids' installation has been revealed as well as the impact of these grids on the exhaust manifold efficiency. The grids have positively influenced on some energy losses within the exhaust manifold and also on relevant dynamie force values affecting the manifold rear wall.
