2. UHMWPE stands for ultra high molecular weight polyethylene.
3. Special thrust bearings are required for high temp. applications over 343_C(650_F)(with6and12-inch shaft extensions). Constructions with carbon steel valves and SST disks may require
special thrust bearings at temps. less than 343_C(650_F).
