The Flow Control Division of Rockwell International has published a new 24-page technical article, "Tests of Asbestos-Free Stem Packings for Valves for Elevated Temperature Service." The article describes a test program conducted to evaluate asbestos- free valve stem packing materials proposed for high-temperature service. Packing gland bolt loads, stem frictional loads, and packing compression were measured with room temperature water at pressures to 6,250 psig (431 bar) and with steam at pressures to 2,200 psig (152 bar). Valve stem diameters from 1 to 4 inches and strokes from 1.68 to 20 inches were also included in the testing.
Approximately 100 packing sets were cycle tested over a 12-month period. In addition, effectiveness of several corrosion inhibitors was evaluated in corrosion tests with 24 packing sets. Several successful packing material combinations are identified.
The Flow Control Division is a leading supplier of high-technology industrial valve and actuator products for the worldwide marine, electrical, power, oil and gas, chemical process and general industrial markets.
