Emerson Process Management has introduced Valve Seat Leak Detection Services. Having valve leak diagnostic information available during the planning stages of a turnaround is a powerful tool that gives plant operations managers, supervisors and engineers greater flexibility to narrow or expand turnaround scopes.
Emerson’s Instrument & Valve Services technicians measure internal valve seat leaks using transducers to detect a leak’s acoustic emission during pre-turnaround walk-downs, and for post-outage verification. The method of "listening" to the sounds of valve seat leakage permits separation of leakage signals from high ambient background noise, increasing leak rate quantification accuracy.
The addition of Valve Seat Leak Detection allows Emerson’s Instrument & Valve Services to offer customers a turnkey solution for valve seat leak detection, diagnostics, open inspect, OEM certified repair, and replacement of Fisher control valves.
Emerson selected Mistras Group as the equipment provider for this offering. This non-intrusive, non-disruptive diagnostic service complements Emerson’s Fisher ValveLink configuration, calibration, and diagnostic tool, FlowScanner valve diagnostic tool and AMS Device Manager.
