This paper presents a method for calculating the water-hammer effect in a hydraulic system with a spring safety valve. A model of the valve including its dynamic functioning is presented. The developed model, enables simulation testing in order to estimate the influence of construction parameters of the spring activated safety valve on pressure changes and on the velocity of fluid flow along the pipe.
