Explanation: Se estas 'ports' forem válvulas para líquidos ou gases, esta é a tradução. Agora, se forem termos de informática eu já não sei dizer...

Reference information: A full port ball valve has an over sized ball so that the hole in the ball is the same size as the pipeline resulting in lower friction loss. Flow is unrestricted, but the valve is larger.
A standard port ball valve is generally less expensive, but has a smaller ball and hence a smaller bore. Flow through this valve is one pipe size smaller than the valves pipe size resulting in slightly greater friction loss than a full port ball valve.
In reduced port ball valves, flow through the valve is one pipe size smaller than the valve's pipe size resulting in restricted flow.
A v port ball valve has either a 'v' shaped ball or a 'v' shaped seat. This allows the orifice to be opened and closed in a more controlled manner with a closer to linear flow characteristic. When the valve is in the closed position and opening is commenced the small end of the 'v' is opened first allowing stable flow control during this stage. This type of design requires a generally more robust construction due to higher velocities of the fluids, which would quickly damage a standard valve.
A full bore (or full port) valve is one where the hole in the ball is equal in diameter to the hole in the pipe. In other words, if you were to look down a piece of pipe which also contained the valve, you would not notice any constriction at the location of the valve.
A reduced bore (also called a standard bore or port) valve is one where the hole through the ball is smaller than the hole in the pipe.
The updates to the menu were made to make the site easy and more intuitive for visitors. Obviously, like any change, this may take a few days to get used to.
The dropdown menus have been divided into two-dimensional panels with similar items grouped together under headings. This eliminates scrolling for those with smaller screens, and also improves readability.
