Material Selection
Guidelines
Usethefollowingstepsasaguidelinefortheselection
of materials:
1. Determine the pressure/temperature rating of the
valve body size and material required. Inlet pressure
and temperature must always be limited by the
applicable ASME pressure/temperature rating.
2. SelectthedesiredtrimstylefromtheAvailable
Configurations specification and from table 4, Shutoff
Classifications.
3. Select desired materials from tables 7, 8, 11, and 12
and figure 12. The temperature capabilities
determined from figure 12 may be further limited by
the temperature capabilities of materials selected
from tables 7 and 12. Refer to figure 12 to determine
pressure drop limits of the valve body-trim
combinations selected.
Installation
The valve must be installed so flow through the valve is
as indicated by the flow direction arrow on the valve
body. Consideration should be given to installing an
upstream strainer, especially if the valve uses a Cavitrol
III cage, Whisper Trim III, or WhisperFlo trim.
Overall dimensions are shown in figures 13, 14, and
15. Face-to-face dimensions are in compliance with
ANSI/ISA-75.08.06. Actual end connection dimensions
conform to ASME B16.25 for buttwelding ends and to
ASME B16.5 for flanged ends.
