Guide line for ball diameter selection in BALL VALVE
(OP)
Hello
I am designing Fire shutoff valve(Ball valve)
Is there any guidelines available for selection of ball diameter in ball valve
And is there any relation available for orifice diameter to ball diameter.
Thanks
John

Draw a cube around the pipe and make the surface of the ball intersect the corners of the cube. That's the minimum sphere diameter.
There wouldn't be much use for a larger ball than that.
