The role of valve stem in process gate valve
Therefore, in selecting the stem material, it must be guaranteed that it is specifiedThe temperature has enough strength, good impact toughness, scratch resistance and corrosion resistance. Valve stem is a vulnerable parts, in the selection of materials should also pay attention to the mechanical processing performance and heat treatment performance, extracted from the www bgfm /, and I hope to help you.
At the same time, it is subjected to the impact and corrosion of the medium, and it also causes friction with the packing.
The valve stem is an important component of the process gate valve. It is used to drive, connect the actuating mechanism or the handle, and directly drive the spool to move or rotate, so as to realize the function of valve switching or regulating. Valve stem in the process of opening and closing of the valve, not only moving parts, stress components, but also seals.
