The method of Laplace valve stroking to control water hammer is presented. Attention is directed to the most frequently encountered of the simple systems: a single pipe originating at an upstream constant head reservoir and terminating at a downstream control valve. In the frictionless systems we can define one functional that permit analyze which is the discharge function to be defined downstream such that minimize the maximum head at the valve. In the systems with friction is proposed one approximate analytical solution determined by the theory of perturbations.
