Abstract

Systems, apparatus, and program code, and methods for monitoring the health and other conditions of the valve, are provided. An exemplary system for monitoring the condition of the gate valve includes a logic module configured to perform the operations of receiving sensor data providing an acoustic emission, vibration, and/or stream level signature and determining the level of lubricity, level of friction, level of surface degradation, and leakage rate at a gate-valve seat interface. An exemplary method for monitoring the condition of the gate valve includes receiving sensor data providing an acoustic emission, vibration, and/or stream level signature and determining the level of lubricity, level of friction, level of surface degradation, and leakage rate at a gate-valve seat interface.

First claim

That claimed is:

1. A gate valve monitoring system for monitoring a condition of a gate valve, comprising:
a gate valve including a housing having an internal cavity and a fluid passageway extending therethrough, and a gate and a valve seat contained within the housing when operably employed, the gate having a gate body configured for slidable contact with the valve seat;
one or more sensors positioned adjacent to or in contact with an outer surface of the housing of the gate va…
