SENSITIZED SEALS
STAR’s Sensitized Steam Turbine Packing is designed to allow the packing ring segment to float on coil springs which readily yield if the rotor makes contact with the packing ring segments. The springs are “sensitized” to accommodate the specific pressures and forces that exist on each packing segment.
