Abstract
This invention pertains to an automated method of testing the spring pack found in motor operated valves. It includes the steps of compressing the spring pack in a test stand while the compressive load applied and the vertical displacement occurring as a result of such loading is measured. This data is sent to a computer that records selected load measurements which correspond to pre-selected displacement values. Afterwards, this data is reported such as by a graph or other report that provides a comparison of the pre-selected displacement values with its respective compressive load.
