ServicesDynamic testing of valve performance
Online valve testing with position feedback measurement

Online valve testing with position feedback measurement can be valuable when an operation team has a list of critical control valves but do not have the resources to overall them all during an upcoming shutdown.

Enero Solutions helps operations team identify valves that should be repaired or replaced for an upcoming shutdown by using a dedicated high-frequency datalogger that measures the result of small changes in valve position demand on the actual valve position feedback and the process variable. With a dedicated valve position feedback measurement, this test can be performed on any type of process, such as:

  • Integrating processes
  • Processes subjected to frequent load disturbances
  • Processes having controlled variables with high signal-to-noise ratios
  • Processes with long time constants and/or deadtime

 

 


An online valve dynamic test can help determine:

  • Valve Deadtime
  • Valve Response Time
  • Valve Deadband
  • Valve Friction
  • Process Gain
