abstract

To assure a leak free scenario when a valve packing is utilized, tests have been developed in order to monitor a group of parameters when service conditions are simulated. These tests enable valve manufactures to have an improved design, and guide end users on efficient packing selection. This paper presents valve packing test devices that provide developers with tools to evaluate properties such as; installation stress, relaxation, stem torque, number of rings and thermal expansion effects. Details of each device are shown, along with typical results of each property evaluated.
