ABSTRACT:
This invention pertains to a method and apparatus for testing the spring pack of a motor operated valve. It incorporates a test stand into which the spring pack is inserted. A horizontal reference plane is attached to the spring pack afterwhich the spring pack is compressed with the vertical displacement of this reference plane being measured. Also measured is the force applied to the spring pack such that afterwards, a comparison of the vertical displacement versus the load applied can be made.
