Butterfly Valves offer high-cycle option.
Press Release Summary:
JAMESBURY® WAFER-SPHERE® Valves are equipped with filled super PTFE shaft seals, 316 SS/woven PTFE shaft bearings, PEEK-filled thrust bearings and extruder rings, and wear-resistant XTREME® seats. Units can provide up to 2 mil cycles with clean media such as oxygen, nitrogen, and hydrogen. Media conditions that preclude use of high-cycle option include media containing acids or chemicals, steam, and temperatures that exceed 325°F.
Original Press Release:
New High-Cycle WAFER-SPHERE® Valves
Two million cycles with clean media.
Northborough, Mass. (October 13, 2005) - A new high-cycle option available with JAMESBURY® WAFER-SPHERE® high-performance butterfly valves results in life cycles four to five times greater than those recorded for valves with conventional components. Much of the research and development work for this advancement was done in cooperation with the air separation industry, where high-cycle WAFER-SPHERE valves are now lasting up to two million cycles.
High-cycle WAFER-SPHERE valves rely on a number of advanced components to reduce deterioration of wear parts and increase cycle life. The low-torque and wear resistance provided by JAMESBURY XTREME® seats was particularly instrumental. Other important high-cycle components include filled super PTFE shaft seals, 316 SS/Woven PTFE shaft bearings, PEEK-filled thrust bearings and extruder rings.
Actual life cycle performance is subject to media, pressure and temperature conditions. Applications such as oxygen, nitrogen, hydrogen and other clean media are ideally suited for this option. There are also a number of media conditions that preclude use of the high-cycle option, including media containing acids or chemicals such as chlorine, bromine and sulfur dioxide, steam, and temperatures that exceed 325°F (163°C).
The air separation industry proved to be an ideal test case for the high-cycle option because it has numerous high-pressure, high-cycle applications, which severely test the longevity of high-performance butterfly valves. It is not uncommon in these applications for on-off valves to cycle every five or six minutes, going from full open to full closed in less than a second. Many of these valves must cycle one million times a year.
With high-cycle option valves, captive users of air separation units have been able to extend maintenance shutdown intervals for as long as two years. This, in turn, has impacted the profitability of such applications as computer chip manufacturing where the value of lost production and subsequent start-up costs after a maintenance shutdown are unusually high.
