Difference between full bore and full port valves
Thread Content
The legend contains these two phrases; I’m not sure how to distinguish between them. Should both be translated as full-bore valve? Q
We call it a “full bore valve”. A full bore (or full port) valve is one in which the hole in the ball has the same diameter as the hole in the pipe. In other words, if you were to look inside a pipe that also contains such a valve, you would not notice any narrowing at the location of the valve.
Yes, they mean the same thing; both are full-bore valves.
A FULL BORE AND FULL PORT VALVE can be translated as “full-bore valve”; a FULL PORT VALVE can also be called an “unreduced-bore valve”. The difference is as follows: BORE SIZE = the smallest diameter of the flow channel (full bore or reduced bore); PORT SIZE = the size of the interface, i.e., the actual inner diameter of the port
! ! ! The OP asked a great question! We need to solve the troubles of Virgo people! :lol
An explanation is provided for reference only: Bore refers to the hole in the ball within a ball valve； For globe valves, the Port refers to the hole in the valve seat ； Anyway, full-bore valves are no problem.
Well, what you say is quite insightful, but I’m still confused. After all, no matter what type of valve it is, it usually has more than one hole on it; you can’t simply use the term \"bore\" to refer generally to \"valve holes\", right? ? ? The locations of the vent valves, relief valves, drain holes, and plug holes can also be considered “valve ports.” How would you explain that? Moreover, I often see people using the terms “valve hole” and “valve body channel” interchangeably, which can be misleading.
