Body Pressure — Temperature Ratings conform to ANSI based on body/
flange rating and body material. As the fluid temperature increases, the
maximum allowable internal pressure decreases. Verify maximum pressures
and temperatures prior to selecting body material and body/flange rating.
NOTE: Approaching limits for
continuous use will reduce trim
life. For continuous use, stay
within half of rated maximum.
NOTE ON BEARINGS: PEEK
Bearings should not be used
for temperatures above
450ºF or flowing differential
pressure above 300 PSIG.
