2. This trim designation not available with the O-ring seat ring gasket construction due to temperature limitations.
3. This trim designation uses the O-ring seat ring gasket construction. See table 12 for O-ring temperature limits. For temperatures greater than 232_C (450_F), flat sheet seat ring gasket with
HTS1 seal ring option (up to 316_C (600_F) is available. Consult your Emerson Process Management sales office.
