Braided graphite packing BuraTAL-Flex 6070

Inconel wirefor valves

Features BuraTAL-Flex 6070 is a graphite-based, multi-layered high performance packing It is manufactured from high-purity expanded graphite yarn (>99 %) combined with a newly-developed high temperature impregnation. For long-term stable use in the high temperature range, the packing is additionally finished with a corrosion inhibitor. The multi-layer structure combines the benefits of maximum possible gap bridging due to the inner Inconel wire reinforcement with protection of the high-quality spindle surfaces in the valves. The packing can be installed without special end rings. Advantages Minimal leakage rates Diameter-independent TA Luft packing solution Ideal for use as a replacement packing Maximum possible gap bridging Operating range Valves Pressure: p = 450 bar Sliding velocity: vg = 2 m/s Temperature Continuous operation: t = -200 °C … +450 °C Steam: tmax = +650 °C Chemical resistance: pH = 1 ... 14 Resistant to hot water, steam, gases, oils, acids and alkalis. Not suitable for use in highly oxidizing acids such as sulfuric and nitric acid in higher concentrations.
