A rotating ball valve assembly includes a rotatable ball element. The rotatable ball element includes a first side portion, a second side portion, and a central passage. One of the first and second side portions includes first and second outwardly projecting pin elements. A sliding sleeve assembly includes a sliding sleeve member having a first guide track with a first force reducing profile associated with the first outwardly projecting pin element and a second guide track having a second force reducing profile associated with the second outwardly projecting pin element. The sliding sleeve member is shiftable relative to the first and second tubular members to selectively pivot the rotatable ball element between an open orientation and a closed orientation.
