Trim Selection Guidelines
Refer to the following descriptions as a guideline for
the selection of appropriate trims.
 Trim 201A– Trim 201A is the standard trim for
carbon steel and alloy steel valve body materials.
This trim is recommended for general or severe
service applications up to 343_C(650_F) or 427_C
(800_F) depending on valve construction. Typical
applications for this trim include services in boiler
feedwater, water, nonsour hydrocarbons, and
steam.
 Trims 202 and 202H– Trims 202 and 202H are
designed for use in high temperature applications
up to 566_C (1050_F). Trim 202H includes special
tolerances required for larger sized HPD and HPAD
constructions, as indicated in table 12, at operating
temperatures above 343_C (650_F).
