\"Turnunion mounted ball over\" is a requirement related to the STYLE in the PIPING MATERIAL SPECIFICATION for ball valves. The whole sentence reads: BOLTED BODY, REPLACEABLE SEAT, REG. PORT, TURNUNION MOUNTED BALL. What does this mean? ? ? ? Thank you everyone for your help
BOLTED BODY is, in my opinion, “a valve body with bolts”. REPLACEABLE SEAT” – “replaceable valve seat”; “turnunion mounted ball over” – it’s possible that you made a typo; it should be “turn union mounted ball over
Is that “reg” in the original post an abbreviation for “regulator”? If so, it refers to a valve on the pipeline. port might be some kind of interface. By the way, I think this of yours isn’t a complete sentence, but just part of one.
The original poster must have made a spelling mistake; it should be “trunnion mounted”, meaning it’s equipped with a bottom shaft. Go and search on the Internet.
OP, you indeed made a spelling mistake; it should be “Trunion mounted ball valve”. The most important thing to understand here is “Trunion”, and this can be easily found out; it refers to “The part of a ball valve which holds the ball on a fixed vertical axis and about which the ball turns” (Reference link: http://www.zy-tech.com/z_glossary/z_glossary.html#Specs ’T’ section)
There is a reference available at http://www.aaron-valve.com/cp.htm, titled “Trunnion Ball Valve”.
Among them, 3 represents “ball”, while 17 represents “Trunnion””
BOLTED BODY: Valve body connected by bolts; REPLACEABLE SEAT: Valve seat that can be replaced; TRUNNION MOUNTED: Ball valve equipped with a trunnion; TRUNNION MOUNTED BALL VALVE: Fixed ball valve; FULL PORT: Full bore (full bore refers to the fact that the opening in the ball of the valve is the same size as that of the pipe); PORT: Refers to the diameter of the valve ball.
