August 23, 2012 - Emerson Process Management introduced Valve Seat Leak Detection Services. Having this critical 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. This powerful 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. "Now, Emerson has the complete valve diagnostics toolbox, including the ability to check pressurized valves which are required to remain closed during inspection," said Tucker Martin, technology services director for Emerson Process Management’s Instrument & Valve Services in Marshalltown, Iowa. "We can provide our customers estimated valve seat leakage to aid them in making more informed decisions for prioritizing maintenance, repair or replacement of valves during turnaround planning." Emerson has selected Mistras Group, Inc., a leading researcher and manufacturer of acoustic emission technologies as 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.
