Flexitallic TR160 / TH894 Stem Sets

Flexitallic TR160 / TH894 Stem Sets are comprised of multiple die-formed rings and loose formed / partially blocked compression packing manufactured from Thermiculite®.

Flexitallic TR160 / TH894 Stem Sets have been developed primarily for high temperature Molten Salt Valve applications. Each set is comprised of a TH894 header and footer ring, loosely blocked to size and shape with a single scarf cut, with two to six TR160 dieformed central rings (stuffing box depth dependent). As standard, the TR160 components are supplied as solid rings, however, they can be split in half to aid installation. Thermiculite® possesses excellent thermal and chemical resistance, consequently, Flexitallic TR160 / TH894 Stem Sets are especially suitable for ‘Molten Salt’ applications where graphite and standard stem packing materials are both chemically and thermally degraded.
