Packings for valves

BuraTAL-Flex 6070 is a graphite-based, multi-layered high performance packing It is manufactured from high-purity expanded graphite yarn (>98 %) 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.

BuraTAL-flex 6224 is a diagonal braided packing made from a combination of Aramid and PTFE yarns with special impregnation. 6224 is the preferred choice for valves, especially low emission applications.

BuraTAL-Flex 6250 is a concentrically braided packing with a dense PTFE yarn sleeve and a carbon yarn core. In addition it contains a special impregnation. 6250 is the preferred choice for fugitive emission, applications and for on/off and control valves.

Chemstar L 6226/L is a diagonally braided 100% PTFE packing, impregnated with a PTFE dispersion. It is manufactured with sintered, high tensile PTFE multifilament yarns with intensive PTFE impregnation. The packing is commonly used in the chemical and food industries.

We can also provide quality monitoring including time certification according to agreed specifications upon request. Chemstar NQ 6226/NQ is a diagonally braided 100% PTFE silk packing, impregnated with a pure PTFE dispersion. According to the Siemens specification for nuclear power stations, the low-chloride PTFE packing is of nuclear grade and suitable as a reserve component in nuclear valves.

Isartherm 6060 is a diagonally braided carbon yarn packing with a PTFE/graphite impregnating agent combined with a silicone oil-free running-in lubricant. It is manufactured from pre-impregnated high performance yarns with the addition of a special lubricant. Isartherm is a special packing for the paper industry and for applications where there are high requirements in terms of functionality and stability.

Isartherm A 6011/A is a diagonally braided graphite fiber packing with a heat-resistant and innovative special impregnating agent. The packing is ideal for use in the high pressure and hot steam range, particularly for valves in power station technology, refineries and the petrochemical industry. It is also well established in practice as a header ring or where the gap geometry is unknown or the sealing surfaces are not optimal.

Isartherm K-Flex 6051 is a braided packing made from expanded graphite, reinforced with textile fibers and with carbon fiber reinforcing corners. It is often used in high pressure and high temperature applications, particularly in power stations and chemical facilities.

Isartherm-Flex 6050 is a diagonally braided packing made from permanently elastic, expanded pure graphite foils. It is used, in particular, in high pressure and high temperature applications. It is a standard packing that can be used in almost all areas of industry.

Isartherm-Flex 6050 is a diagonally braided packing made from permanently elastic, expanded pure graphite foils. It is used, in particular, in high pressure and high temperature applications. It is a standard packing that can be used in almost all areas of industry. It is also ideal as a header ring to prevent gap extrusion. Reinforced with Inconel fibers, impregnated with corrosion inhibitor.

Rotatherm 0901/B are precompressed rings made from permanently elastic expanded pure graphite (≥ 99.85% graphite) without binders or fillers.

Rotatherm S881/B are precompressed rings made from pure graphite (≥ 99.85%) with embedded stainless steel reinforcement optimally positioned to suit the cross-section. No metal-to-metal contact with spindle or housing. They are ideally used as chamber sealing rings in high temperature and high pressure valves to avoid extrusion (particularly through large gaps).

Rotatherm tape 0902 is nuclear grade pure graphite tape (purity ≥ 99.85 %). It is suitable for sealing or packing valve spindles during servicing. They are used to quickly and easily create working packing rings inside the valve

Thermoflon TR 6232 is a PTFE packing made from high purity graphite-incorporated PTFE without the addition of lubricants or fillers. It is ideal as a header ring to prevent gap extrusion. The special yarn structure also makes it suitable for temperature cycling applications.
