Flowserve Corp. has announced Flowserve ValveAnalysis, a software plug-in for Emerson Process Management's AMS Suite of asset management tools. The plug-in enables AMS users to run diagnostic signatures for Flowserve valves, actuators and positioners, providing information that can be used to maximize equipment performance. The software integrates with the Flowserve Logix 520si and 3200IQ HART positioners. Unlike similar competing software packages, it is said the plug-in does not bypass AMS, ensuring that a complete device history is always maintained. Informative diagnostic tests that can be run with ValveAnalysis include Ramp Signature and HDL.
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. HDL data can assist in making decisions that can improve maintenance procedures and maximize efficiency.
