Form of Groove on Ball (Floating Ball Valve)

Form of Groove on Ball (Floating Ball Valve)

(OP)
hello

why the form of groove on ball for locating end of stem is curve type? why is not a simple pocket?



thank you?

RE: Form of Groove on Ball (Floating Ball Valve)

The stem has a rectangular portion which fits into the slot allowing the ball to be rotated as the stem is turned.

RE: Form of Groove on Ball (Floating Ball Valve)

To increase the bearing surface of the slot without affecting the area where the seal rings are.

RE: Form of Groove on Ball (Floating Ball Valve)

Cutting the slot is faster and easier using a round mill cutter. This way it can be cut in one quick step. End milling a slot takes longer to cut and the accuracy of the slot width is not as consistent.
