Regular port vs reduced port

WebIn reduced bore (sometimes reduced port) ball valves, flow through the valve is one pipe size smaller than the valve's pipe size resulting in the flow area being smaller than the pipe. As the flow discharge remains constant and is equal to the area of flow (A) times velocity (V), A 1 V 1 = A 2 V 2 {\displaystyle A_{1}V_{1}=A_{2}V_{2}} the velocity increases with … WebThe difference can be summed up fairly simply: Full port: The valve port is the same diameter as the pipe. Standard port: The valve port is smaller than the pipe’s diameter. …
