A new method for preventing water hammer and cavitational hammer in pipeline systems by an adaptive control of the valve closing process has been developed. To this end, the shut‐off valve has been equipped with an innovative hydraulic brake system that acts onto the rotation axis of the valve and combined with a swing check valve. The described system does not need any additional energy source and adapts automatically to changes of the pipe system parameters, so that it proves advantageous as against the conventional damping system which delays valve closing in a fixed manner.
