Braided graphite packing BuraTAL HT 9650/HT

carbon fiber-reinforced

Features BuraTAL HT is a completely new design of packing set consisting of the following components: Braided end rings of expanded pure graphite with carbon fiber-reinforced corners High-density expanded pure graphite sealing discs as a diffusion barrier Specially impregnated adapter rings made from high-density, expanded pure graphite Lower-density sealing ring made from expanded pure graphite with a smooth, friction-reducing coating. Advantages Low spindle torques Minimal leakage rates Operating range Valves Pressure: p = 300 bar Pressure: p as per TA Luft: 80 bar Sliding velocity: vg = 2 m/s Temperature Continuous operation: t = -200 °C … +400 °C Steam: tmax = +550 °C Chemical resistance: pH = 0 ... 14 Resistant to most chemicals (solvents, hydrocarbons, acids, alkalis), steam, alcohols, oils, water etc. Standards and approvals TA-Luft Leakage test to API 622 Fire safe to API 589 Recommended applications Industries Process industry Petrochemical industry Chemical industry Mineral oil industry (refineries) Components Valves Variants 9650/HTB (with live-loading System) Notes Valve sealing kit – for high pressures and temperatures, particularly in TA Luft applications, for standardization without live-loading.
