Abstract
A ball valve having a main body portion with a throughbore and a rotatable ball valve closing off the throughbore. The ball is of resilient plastic and is comprised of a pair of interconnected sides defining a slot therethrough. The valve body portion has cams associated with the throughbore engageable with the ball side when the same is rotated. The sides, in a first position, close off the throughbore, the cams engage the flexible sides and camming the same into fully seated closure of the throughbore. When rotated away from engagement with the cams, the slot in the ball valve is aligned with the throughbore allowing fluid flow therethrough.
