TA Luft and EN15848 Valve stem packing sets

Graphite Filament yarn with High Temperature Graphite impregnation Practical useful application data: max. temperature in oxidizing atmosphere: +450 °C Characteristics Yarn of highest puricity >99 % C content Universally chemical resistant The addition of high temperature Graphite impregnation increases the cross section density and works as a stable pressure cushion for the graphite fiber Flexible, ressistant ot wear and surface protecting Excellent in temperature cycling, since graphite has a similar coefficient of expansion as steel Excellent as bullring for packing made of expanded graphite Operating range Pressure [p max]: 30 bar, Velocity [v max]: 15 m/s Pressure [p max]: 300 bar Temperature: t = -40… +600 °C pH: 1 - 14 Density: 1.00 g/cm³ Practical useful application data: max. temperature in oxidizing atmosphere: +450 °C Main application Valves Fittings Gate valves Flaps Suitable for Power plant technology Boiler houses High pressure- and high temperature...
