Figure 8. Typical Trim Used for All Valves Except NPS 4 and 6 Fisher ED with Whisper Trim III Cage and WhisperFlo
Cage
Notes:
Do not exceed the maximum pressure and temperature for the pressure rating of the valve material used, even though the trims shown may have higher
capabilities.
Be especially careful to specify service temperature if trim 3 or 37 is selected, as different thermal expansion rates require specialplug clearances. Specify trim 37H
for temperatures above 210_C (410_F). Specify trim 3H for temperatures above 427_C(800_F).
Trim 29 may be used up to 103 bar (150 0 psi) with clean, dry gas.
Use trim 27 instead of trim 29 for nonlubricating fluids such as superheated steam or dry gases between 149 and 316_C (300 and 600_F).
