ValveAnalysis™ Software is a software plug-in that works with Emerson Process Management's AMS Suite to run diagnostic signatures for the company’s valves, actuators and positioners. ValveAnalysis integrates with the Flowserve Logix® 520si and 3200IQ HART® positioners. ValveAnalysis does not bypass AMS, ensuring that a complete device history is always maintained. Informative diagnostic tests 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 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.
