1. Temperature limits apply to seating or packing arrangements only. Complete valve assembly temperature limits may differ, refer to appropriate pressure/temperature ratings. For
more information on packing selection, reference Fisher Packing Selection Guidelines for Sliding-Stem Valves, Bulletin 59.1:062 (D101986X012).
2. Extension bonnets and NOLEEK bellows bonnets are applicable for the 24000SVF stainless steel body assembly ONLY.
3. PTFE packing can be used in cryogenic service but becomes stiff.
