ITT Engineered Valves was recently featured in an article for Machine Design
website entitled, “Discovering Defects: Design for Reliability Products.” The article discusses how the ITT Engineered Valves team recently redesigned a traditional diaphragm valve for a biopharm customer by eliminating the failure modes. In doing so, they ‘designed out the defects,’ with which the client had historically struggled. The resulting design, called the EnviZion diaphragm valve completely changed the performance, reliability, and quality impact of this component. Most impressive is the Estimated Total Cost of Ownership (TCO) savings of over one decade by investing in 1,000 ITT EnviZion Valves vs. the traditional Diaphragm Valve: $1,600,000.
Design for Reliability (DfR), is an examination of a project and its assets spanning all phases, while considering the viewpoints of stakeholders across the full project lifecycle. The main drivers of DfR are reduction in total cost of ownership (TCO) and prevention in strategic errors. DFR is a methodology that leads to “defect discovery” as a way to categorize previous lessons learned, best practices and industry expertise to eliminate, decrease or mitigate failure modes so they don’t become future defects. The approach blends aspects of statistics, reliability theory, engineering analysis and subject matter expertise to ensure, evaluate, predict and verify the application of a robust design.
The purpose of designing out failure modes or modifying them is to avoid errors, and the cost of an error depends on where you catch it. In DfR programs, the design phase is a good place to start. Read the article in its entirety and learn more about the DfR value proposition HERE
