摘要： 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 fully opened position and vice versa with a rotation of the valve member of less than or equal to about forty-five degrees.

摘要： A ball valve having reduced torque requirements for rotation is presented. Torque reduction is realized by providing a shaped sealing back member to provide a back force behind essentially the entire sealing surface of the downstream seal. Torque reduction is also realized by providing a dynamic sealing configuration that varies the sealing force over the valve's operating pressure conditions. An initial bias sealing force is applied by a spring member which also provides a low uniform as-assembled valve torque. As fluid pressure increases, the sealing pressure also increases as an o-ring is forced along a ramped surface of the seal. As inlet pressure decreases, the o-ring is allowed to back down the ramped surface to reduce the sealing force against the valve member. This sealing configuration allows for reverse flow or improper installation of the ball valve, and bottoms out to maintain a sealing force at higher back pressure conditions.
