Abstract
A valve system includes a valve, which is operated by a pneumatic actuator and forms part of an industrial plant, wherein the valve system includes a diagnostic system that includes either a pressure detection unit for acquiring data on a pressure variation in the pneumatic actuator and/or at least one acoustic detection unit for detecting an acoustic variation in the valve system, where the valve system additionally includes a pilot valve, preferably a solenoid valve, which controls the pneumatic actuator, an electrical connection to an electrical power supply network supplying the pilot valve to supply electrical power to either the pressure detection unit and/or the acoustic detection unit, and where the diagnostic system additionally includes a measurement unit for identifying changes in the electrical power supply network for the pilot valve to identify a starting point of a closing or opening action of the valve.
