Abstract

A valve integrity manager is coupled with a servo or stepper motor to direct micro stroke testing of emergency shutdown valves. During testing, the system orders a closure of 20-25% of an emergency shutdown valve, providing data that either confirms the operability of the valve or a deficiency, while minimizing any effect on process variables.
