This paper reports on valve stroke timing test equipment developed and tested for use in a nuclear power plant main control room that can provide significant advantages to the user for valve surveillance testing required by the Nuclear Regulatory Commission. The equipment is particularly suitable for Motor-Operated Valves (MOVs) because of its accuracy and repeatability that is necessary to detect the effects of small changes in actuator motor RPM.
