1. Special gasket retainer bolts are required for over 538_C (1000_ F).
2. Special retaining ring screws for single flange valves over 538_C (1000_F).
3. Special thrust bearings are required for high temperature applications over 343_C (650_F) (with 6 and 12 inch extensions). Constructions with carbon steel valves and SST discs may require
special thrust bearings at temperatures greater than 343_C(650_F).
