BuraTAL 70 9650/70

Special variation of a sealing set for valves at high temperatures. Rotatherm- high precision seals deliver optimal sealability, low diffusion and exceptional service life. Complemental to the very low wearing of the sealing faces this high temperature and high pressure sealing set is able to adjust gaps of the valve components as well. A special version (graphite rings with a thin, elastic stainless steel cap to bridge large gaps and reduce oxidation) is available for applications above 550 °C.
