The report documents testing conducted to establish a seat and poppet material andor sealing concept for use in chlorine pentafluoride ClF5 attitude control system ACS valves. Test results of nickel-, iron-, tungsten-, and zirconium-based materials in the flat-on-falt sealing concept as well as a sapphirecopper lip-seal concept are discussed. In tests conducted to date, two varieties of tungsten carbide in the flat-on-flat configuration Kennametal 96 and Kennametal 801 are the only materials that have met the leakage requirement of 30 scc heliumhour after 100,000 actuations in ClF5.
