Ball Valve with Offset Straight Through Flow
First Claim
1. A ball valve having a fully open position to allow fluid flow through the ball valve, and a fully closed position to prevent fluid flow through the ball valve, the ball valve comprising:
- a housing having an inlet and an outlet and an internal cavity positioned between the inlet and the outlet, wherein a flow path extends through the housing and between the inlet and the outlet; and
a non-spherical ball valve member positioned within the internal cavity and within the flow path, the non-spherical valve member having a passageway therethrough that is selectively alignable with the flow path, the non-spherical valve member rotatable within the internal cavity to transition the ball valve between the fully open position and the fully closed position and vice versa.

Abstract
A ball valve with offset straight through flow is provided. The ball valve has a housing having an inlet and an outlet and an internal cavity. A non-spherical ball valve member is positioned within the internal cavity. The valve member is mechanically coupled to a valve stem extending from the internal cavity to an exterior of the housing such that rotation of the valve stem results in a like rotation of the valve member. The ball valve has a fully closed position wherein fluid flow therethrough is prevented. The ball valve member also has a fully opened position where fluid flow therethrough is allowed. The ball valve can transition from the fully closed position to the frilly opened position and vice versa with a rotation of the valve member of less than or equal to about forty-five degrees.

9. A ball valve having a fully open position to allow fluid flow through the ball valve, and a fully closed position to prevent fluid flow through the ball valve, the ball valve comprising:
-
a housing having an inlet and an outlet and a flow path extending therebetween; a ball valve member positioned within an internal cavity of the housing between the inlet and the outlet and within the flow path to selectively transition the ball valve between the fully open and fully closed positions, the ball valve member having a straight passageway; and wherein the passageway has a non-circular cross sectional profile and defines a valve member flow axis passing through a center of the passageway. - View Dependent Claims (10, 11, 12, 13, 14)

15. A ball valve having a fully open position to allow fluid flow through the ball valve, and a fully closed position to prevent fluid flow through the ball valve, the ball valve comprising:
-
a housing having an inlet and an outlet and an internal cavity positioned between the inlet and the outlet, wherein a flow path extends through the housing and between the inlet and the outlet; a valve member positioned within the internal cavity and rotatable therein such that rotation of the valve member of less than or equal to about forty-five degrees transitions the ball valve from the fully open position to the fully closed position and vice versa. - View Dependent Claims (16, 17, 18, 19, 20)
