API 600 & 602 gives the list of Trim materials that can be used in the valve. ASTM A410 (13Cr), ASTM A316, Alloy 20 (19Cr-29Ni), and Monel (Cu-Ni Alloy) are commonly used trim grades. Refer to the figure below to find a typical Valve trim chart as provided by API 600 and API 602.

API 600 trim table lists typical material combination for gate valve trims showing the material for seating surfaces and internal parts.

Valve trim refers to the operating parts of a valve that are usually exposed to the process fluid. In this article, you will learn more about the meaning of valve trim, review a valve trim chart, learn about the material selection process, and review the selection process in action by comparing two common trims: trim 5 vs. trim 8.

Dec 31, 2021 · Valve trim parts may be constructed of assorted materials because of the different properties needed to withstand different forces and conditions. Bushings and packing glands do not experience the same forces and conditions as the valve disc and seat (s).

API 600 & 602 gives the list of Trim material that can be used in the valve. The most common trim grades are ASTM A410(13Cr), ASTM A316, Alloy 20 (19Cr-29Ni), and Monel (CuNi Alloy). Here in the image, you can see the simplified chart of the trim material.

Discover everything you need to know about valve trim, including plug profiles, parts, material selection, and a comprehensive valve trim chart. Learn how to choose between different trims like Trim 5 and Trim 8 for optimal valve performance.

Different Types of Control Valve Trim are based on Seat material, based on valve trim function and valve stem guide type.

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.

API 594 trim material no. 1, 5, 5A, 8, 9, 10, 12, 13, 14, AA, for body seating surfaces; plate or discseating surfaces.

API 600 valve body, bonnet, and cover materials (ASME B16.34, Material Groups 1, 2, and 3) along with associated valve trim materials (trim numbers, Table 8) and ASTM A193 and ASTM A194 specification bolting materials.
