Overview

This course is designed to teach the techniques necessary to collect and interpret valve diagnostic tests performed using AMS ValveLink™ software.

This 3 days course uses classroom lectures and hands on workshops to teach the student to interpret and analyze diagnostic data obtained using FIELDVUE™ Digital Valve Controllers and

AMS ValveLink™ software. Students will perform diagnostic tests on a variety of valve/actuator combinations and use the data to determine bench set, dynamic error band, seat load, spring

rate and other pertinent parameters.

Students will also perform comparison tests on valves/actuators containing assembly or operating flaws and use the data for troubleshooting purposes.

Students who take this course will be able to:

• Use/understand diagnostic terminology.
• Interpret AMS ValveLink™ diagnostic traces and determine bench set, packing friction, seat load, spring rate, dynamic error band and a number of other common valve parameters.
• Use diagnostic traces to troubleshoot problems in valve/actuator assemblies.
