1. For high-temperature air, hydrocarbons, and certain other chemicals and solvents. Not for use with steam or ammonia. Not recommended for water above 82_C (180_F).
2. Has ex cellent moisture resistance to hot water and steam and may be used with most fire-resistant hydraulic oils, but cannot be used with petroleum-based fluids and other hydrocarbons.
3. Cannot be used with fire-resistant hydraulic oils.
4. These parts not used with 137 mm (7 inch) ports or larger.
5. These materials not limiting factors.
6. This material may be used in temperatures up to 260_C(500_F) for oxidizing service.
7. Standard for NPS 8 valve regardless of cage and all NPS 1 thru 6 valves with Cavitrol III cages, optional in NPS 1 thru 6 valves with other than Cavitrol III cages.

1. Temperatures above 232_C (450_F) require PEEK anti-extrusion rings and spring-loaded seal ring. This option allows ET construction to be used up to 316_C (600_F) for non-oxidizing service
and 260_C(500_F) for oxidizing service.
2. Lubricating service allows usage to 232_C(450_F)
3. Same material also used for bottom flange, if required. Restricted trim and full-sized limits are the same.
4. May be used down to
-254_C(-425_F) if manufacturing process includes Charpy impact test.
