Abstract
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.
Claims21
A valve assembly, comprising:
- a valve body having inlet and outlet flow passageways connected by a valve chamber;
- 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;
- and
- a linear actuation member slideable to engage the bore or the ball/bore interface to assist in moving the ball valve member to the valve closed position.
A method, comprising:
- coupling a valve assembly to a conduit, the valve assembly including:
- a valve body having inlet and outlet flow passageways connected by a valve chamber;
- 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;
- a primary actuation member coupled to the ball valve member;
- and
- a separate secondary linear actuation member slideable to engage the bore or the ball/bore interface;
- and
- activating the primary actuation member to initiate a movement of the ball valve member from the valve open position toward the valve closed position;
- and
- activating the secondary linear actuation member to finalize the movement of the ball valve member to the valve closed position.
