Flowserve has announced the launch of Flowserve ValveAnalysis, a software plug-in for Emerson Process Management AMS Suite of asset management tools. Flowserve ValveAnalysis enables AMS users to run diagnostic signatures for Flowserve valves, actuators and positioners, providing key information that can be used to maximise equipment performance. Adding informative diagnostic signatures to the calibration and alarm functions already found in AMS, Flowserve ValveAnalysis allows users to increase the flexibility of their Emerson system and preserve the value of their Flowserve equipment base. ValveAnalysis integrates with the Flowserve Logix 520si and 3200IQ HART positioners. For positioners with actuator pressure management, the Ramp Signature test plots command versus position and compares this data to cylinder pressures. The Ramp signature test can be used to identify problems such as leaks in tubing fittings, improperly aligned plugs and seats, loose linkage, broken actuator springs, and sticky spool valves. The ValveAnalysis HDL test calculates the four standard diagnostic signatures – hysteresis, deadband, repeatability and linearity – by opening and closing valves. These signatures can be saved for future comparison to determine changes in equipment performance over time.
