V150 or V300 WCC (or 1.0619 Steel), CF3M (or
1.4409 SST), CG8M, LCC, M35-2, CK3McuN, CD3MN,
and CD3MWCuN Valves:
Consistent with CL150 for
V150 or CL300 for V300 pressure-temperature
ratings per ASME B16.34 or with PN
pressure-temperature ratings shown in table 1.
Note:
CF3M is the standard material offering in Europe and
Asia-Pacific. 1.0619 Steel and 1.4409 SST are also
standard material offerings in Europe.
V200 WCC, CG8M, and LCC Valves:
Consistent with
applicable pressure-temperature ratings in table 1 per
ASME B16.34.
CW2M:
Consistent with applicable
pressure-temperature ratings shown in table 6.
Do not exceed the material temperature capabilities
shown below or the pressure drop limitations.

Fisher TCM Plus or Ultra Ball Seal (Forward Flow):
Class VI per ANSI/FCI 70-2 and per IEC 60534-4,
Flat Metal Ball Seal for NPS 3 through 12 only
(Forward Flow):
Class IV per ANSI/FCI 70-2 and per IEC
60534-4,
HD (Heavy Duty) Ball Seal (Bidirectional Flow):
0.01%
of valve capacity; Class IV per ANSI/FCI 70-2 and IEC
60534-4; Maximum allowable pressure drop in
reverse flow is 6.9 bar (100 psi);
High Temperature HD (Heavy Duty) Ball Seal
(Bidirectional Flow):
Class III per ANSI/FCI 70-2 and
IEC 60534-4
Flow Ring Construction (Bidirectional Flow):
5% of
valve capacity at full travel
Micro-Notch Ball with HD Seal:
4 SCFH (Leakage rate
equivalent to Class IV for standard ball. This is based
on the capacity of a standard ball.)
