The removable and replaceable check valve internal parts that come in contact with the flow medium are collectively termed as valve trim. These parts include valve seat(s), disc, glands, spacers, guides, bushings, and internal springs.
The valve body, bonnet, packing, et cetera that also come in contact with the flow medium are not considered valve trim.
Dual plate check valve trim parts may be constructed of assorted materials because of the different properties needed to withstand different forces and conditions.
Flow-medium properties, chemical composition, pressure, temperature, flow rate, velocity and viscosity are some of the important considerations in selecting suitable trim materials. Trim materials may or may not be the same material as the valve body or bonnet.
The number corresponding to material used in API 600 and API 602 are termed as trim numbers.
