For the design of hydraulic cylinders, speed and power must be calculated in dependence of the existing pressure in the cylinder space and the volume flow available.
For this, the admissible values for the operating pressure in dependence of the pressure series and the admissible oil speed in the hydraulic ports must be taken into account.
