F-port valve balls are very similar to T-port valve balls and L-port valve balls. As known as, LL-port valve balls.

F-port valve balls are used to take two inlet flows and combine them to flow out through one common outlet port but always has one inlet/ outlet at the bottom of valve ball.

This can be used for splitting, dividing, and diverting flow. They can act like L-port valve balls and divert flow from one inlet port to the other two outlets..

With the F-shape drilled bore, the fluid can be directed from X axis to Y axis which is very different from L and T port valve ball.
