Valve code translation
Thread Content
I have some questions regarding the translation of the various codes for valve materials. For example, for the following valves: 1. GATE VALVE, RF, CL600, BB, 0S&Y, ASTM A105, ANTI-H2S; SEAT: 316; WEDGE: STL; STEM: A182 F316; HANDWHEEL. 2. GATE VALVE, BW, CL900, PSB, 0S&Y, ASTM A351 CF8C; SEAT: A351 CF8C+STELLITE; WEDGE: A351 CF8C+STELLITE; STEM: A638 Gr.660; HANDWHEEL, SCH80S. I would appreciate it if someone could help translate the terms in red.

The translation on the second floor is very accurate and comprehensive; thumbs up!
Thank you to the expert on the second floor for sharing: handshake
It was only later that I realized that each project actually has a valve specification sheet, which contains detailed translations of the codes. I didn’t pay attention before
What is the difference between CF8C and CF8? Is there a significant difference in their cost prices?
