he amount of pressure nearest the point of performing work at the output end of a pneumatic system. The system operating pressure is used to specify the capability of valves and actuators.
Operating pressure is the ideal pressure at which an element can operates effectively. Its range lies between minimum to the maximum pressure. out of this range of operating pressure the element may get destruction.
The operating pressure is related to the vapor pressure of fluids, maintaining the designed flow and head in case of a pump and in stationary equipment refer the API & ANSI guidelines.
