What is a stainless steel ball valve used for?
Thread Content
Hello everyone. I’ve seen many stainless steel ball valves, and they all have these two protrusions on the valve body (within the red box). What are they used for?
Is it the casting point during the casting of the stainless steel valve body? Or what? There are also indentations at all 4 ends
One of its functions is to increase strength, and this design allows for material savings while enhancing strength. :)
Two radial reinforcement ribs are added to the outer surface of the cylindrical ball valve to ensure the strength of the valve body during opening and closing
It’s just a matter of cutting corners – by reducing the size of the valve body and placing it here, it can help prevent casting porosity, but it’s not very useful. The only advantage is that it allows for threading in a support bracket; after all, high-platform ball valves are used almost everywhere these days
Haha, to be honest, I checked a few stainless steel ball valves just now and they didn’t have this setting either; so there is indeed some trick to it! ;P
There are too many products on the market, and there are no unified standards for their production
It should be to install a valve locking device; some of the valves on our imported equipment come equipped with such locking devices. In China, many implementations are not done properly; they are just superficial and cannot be installed, as if someone is simply imitating what others have done. I can’t send pictures; the difference is obvious when compared.
