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 Notes Valve sealing kit - for high pressures and temperatures, particularly in TA Luft applications, for standardization without live-loading. Article numbers of variants 9650/HTB (with live-loading System) Forms of supply • Custom-made packing sets • Individual dimensions available upon request Recommended applications Industries • Process industry • Petrochemical industry • Chemical industry • Mineral oil industry (refineries) Components • Valves eagleburgmann.com [email protected] All technical specifications are based on extensive tests and our many years of experience. The diversity of possible applications, however, means that they can serve only as guide values. We must be notified of the exact conditions of application before we can provide any guarantee for a specific case. This is subject to change.
