摘要:
A valve, system and method for controlling flow of fluid about a wellsite component of a wellsite are provided. The wellsite component has a flowline to pass the fluid therethrough. The valve includes a valve housing, a cage having holes therethrough positionable in selective fluid communication with the flowline, a valve plate operatively connectable between the valve housing and the cage (the valve plate having a sealing surface thereon), and a spool assembly comprising a spool slidably positionable in the cage. The spool assembly is selectively positionable in sealing engagement with the sealing surface of the valve plate to define a sealing interface therebetween, and is movable between an inlet position defining a fluid intake path and an outlet position defining a fluid outtake path whereby the fluid is selectively diverted through the wellsite component.
