NOTES:
Use trim 27 instead of trim 29 for nonlubricating
fluids such as superheated steam or dry gases
between 149C (300F) and 232C (450F).
Do not exceed the maximum pressure and temperature
for the pressure rating of the body material used,
even though the trims shown may have higher capabilities.
Trims 4 and 29 may be used up to 99 bar (1440 psi) with clean
dry gas. For process fluids other than clean dry gas,
Use trims 4 and 29 only up to 21 bar (300 psi).
Trims 1, 27, and 37H temperature limits can be extended
to 316C(600F)fornon-oxidizingserviceor260C
(500F) oxidizing service if PEEK anti-extrusion rings
are used with spring-loaded seal rings.
Use trim 37H instead of trim 37 for temperatures
above 210C (410F). Requires anti-extrusion rings and
spring-loaded seal rings for temperatures above 232C (450F).
