Urgent! What do WCB/STL mean in terms of valve material? Where can I find this standard
WCB/STL denotes carbon steel for the valve body, with Stellite cemented carbide for the sealing surface
WCB/STL indicates that the valve body is made of carbon steel, while STL denotes that the sealing surface is clad with Stellite cemented carbide
WCB/STL denotes carbon steel for the valve body, while STL refers to Stellite cemented carbide used for the sealing surface
WCB/STL indicates that the valve body is made of cast carbon steel, while the sealing surfaces of the valve body and seat are welded with Stellite alloy. The purpose is to resist medium erosion and cavitation. Generally, the valve spool and valve ball are forged parts.
