Document Type and Number:
WIPO Patent Application WO/2018/209564
Kind Code:
A1
Abstract:
A method of estimating a remaining life of a valve is disclosed, comprising steps of collecting valve actuation force data; calculating an average value of the valve actuation force data in at least one of a plurality of actuation cycles; estimating a remaining life of the valve using a model based on the calculated average values of the valve actuation force data obtained from the at least some of the plurality of cycles and a valve actuation force limit. A valve controller (20, 21) of estimating a remaining life of a valve is also disclosed.
