OPTIONS : LEVER OPERATION / LOCKING OPERATION
A full port or more commonly known full bore ball valve has an over-sized ball so that the hole in the ball is the same size as the pipeline resulting in lower friction loss. Flow is unrestricted but the valve is larger and more expensive so this is only used where free flow is required, for example in pipelines which require pigging.
Floating Ball Valve– A floating ball valve is not held in place by a
trunnion, and instead is attached only to the stem. This sometimes causes the
ball to float slightly downstream. However, when this happens, the ball presses
against the seat, creating a positive seal.
