Provided is a valve assembly and method for opening and closing thereof. The valve assembly, in one aspect, includes a valve body having inlet and outlet flow passageways connected by a valve chamber, and a ball valve member having a bore there through creating a ball/bore interface, the ball valve member located in the valve chamber for selective rotation between valve open and valve closed positions to control flow through the valve assembly. The valve assembly, according to this aspect, includes a linear actuation member slideable to engage proximate the ball/bore interface to assist in moving the ball valve member to the valve closed position.

Advanced loading method for ball rotation cutting and method of use therefor

A method of actuating a subsea tree comprising opening a valve assembly by transferring a first volume of fluid into a first chamber and closing the valve assembly from the open position to a shear position via a gas charged valve actuator in response to the transfer of fluid out of the first chamber. Shearing a workstring positioned within an axial bore of the valve assembly with the valve via the gas charged valve actuator. Closing the valve from the shear position to a closed position with one or more gas charged push rods to isolate the wellbore above from the wellbore below the closed valve. The shearing force generated from the gas charged valve actuator is greater than the closing force of the one or more push rods.

A system includes a ball valve positionable along a fluid flow path of a wellbore. The ball valve is movable between an open position, where fluid is able to flow through the fluid flow path, and a closed position, where the fluid is prevented from flowing through the fluid flow path. The system also includes an electric motor coupled to a drive system within a trunnion of the ball valve. The electric motor drives rotation of the ball valve to move the ball valve between the open position and the closed position. Further, the system includes a power source electrically coupled to the electric motor to provide power to the electric motor.
