According to the GB T 32808-2016 standard, T refers to a control valve of the sleeve type; what exactly is this type of valve? 6 indicates the welding method – specifically, whether it is socket welding or butt welding? Y indicates that the material of the sealing surface is cemented carbide; what specific alloy is it? There is no detailed explanation in the standards either. Please let friends share their opinions.
T – Control valve; 6 – Welding joint; 1 – Multi-stroke plunger type; Y – Sealing surface; made of cemented carbide
For socket welding, as for the cemented carbide material, you need to ask the client. If it’s for steam use, it’s very likely STL, the sleeve type; just search on Baidu
