Apparatus for monitoring of valves and method of operating the same

A valve includes a valve stem assembly including at least one wall and at least one passage at least partially defined within the valve stem assembly. The at least one passage defines a first opening. At least one portion of the at least one wall defines an erosion site that is configured to undergo...

Beschreibung
Zusammenfassung:	A valve includes a valve stem assembly including at least one wall and at least one passage at least partially defined within the valve stem assembly. The at least one passage defines a first opening. At least one portion of the at least one wall defines an erosion site that is configured to undergo contact with solid particles such that a second opening of the passage is defined. The valve also includes at least one sensing device coupled in flow communication with the at least one passage through the first opening. The at least one sensing device is configured to transmit a signal representative of an increased fluid flow through the at least one passage.
