`Inferring Aseptic Valve Diaphragm Maintenance

`
`Emerson’s Tom Holemans shared a recent problem-solving story with me about a pharmaceutical manufacturer’s desire
`to reduce aseptic valve maintenance costs and increase overall availability by switching from a preventive to predictive
`maintenance approach.
`
`As a process industry specialist with ASCO Numatics my role is to work closely with
`manufacturers to help identify ways we can help them address their issues by using our
`technologies. I visited a pharmaceutical manufacturer recently who has over 6,000 aseptic
`diaphragm valves installed in the plant.
`
`
`
`It is highly important to them for plant
`availability and product quality reasons that the
`diaphragms in the valves do not fail. They have
`a preventive maintenance programme in place
`that means that each diaphragm must be
`changed every 6 months. This is a time
`consuming and costly process equating to
`approximately 600 man days per year. They
`wanted to move to predictive maintenance for
`these valves but were not sure the technology
`was available to enable them to do that.
`
`Further investigation revealed that the valves
`were being piloted by valve islands–a bank of
`solenoid valves connected to an electronics
`module–which were in turn connected to the
`DeltaV control system via a Profibus DP
`communications network.
`
`We were able to demonstrate that by installing
`ASCO Numatics valve islands with the G3
`electronics module they would be able to use
`the DeltaV system to count the number of
`cycles that each valve makes. This
`measurement can be used to predict
`diaphragm failure, enabling diaphragm change-
`out periods to be extended over time as they
`gather information and experience.
`
`In addition to the inferred diagnostics for the aseptic valves the G3 provided onboard diagnostics with a
`graphical interface, enabling valve island faults to be diagnosed quickly further aiding availability.
