FIGURE 1-3: VALVE CONFIGURATION DURING A PERTURBATION
There are six families of perturbations. A description of each follows. The properties (e.g.
duration, maximum pressure) for the perturbations are established in the
flexiWare
software.
For detailed information about perturbation properties, refer to the
flexiWare
user manual.
