FMEA RPN Scoring Consistency Matrix
Download as PPTX, PDF0 likes128 views
The document outlines a Failure Modes and Effects Analysis (FMEA) for a control valve, detailing Risk Priority Numbers (RPN) for different failure modes related to water isolation and detection. It includes severity ratings for issues such as plugged output, delayed operation, and valve failures. A scoring consistency matrix is used to evaluate redundancy and detection methods before and after implementing changes.
