Seeking advice on the two-way pressure-resistant structure of flanged butterfly valves
Thread Content
For conventional flanged butterfly valves, the sealing surface is directly machined on the valve body, after which D507 or STL materials are welded onto it. There are currently some low-temperature flanged butterfly valves, and we plan to use molds designed for normal temperature applications; however, the technicians say that a movable seat must be used instead of welding directly on the sealing surface. What is the structure of such a movable seat? Thank you.
It would be best to send a picture or a schematic diagram. It would be better to describe based on the picture. But the instructor is the best on-site teacher – they provide hands-on guidance, and if you don’t understand something you can ask questions. How great is that? It’s a waste not to make use of such resources;P
