The protrusion on the valve and its purpose
Thread Content
What are the many protrusions on the outer surface of this PTFE-lined pneumatic actuator for?
I’ve seen this for the first time; the protrusion seems to be welded on separately, and it’s not clear what its purpose is

But the valve material shown in the diagram is WCB, so it’s impossible for the temperature to be very low. It’s hard to say about such uses
Is there a vacuum condition, used for fixing the fluorinated lining?
