摘要：Methods and apparatus for selectively blocking or redirecting flow with a valvethat compensates for misalignment between a seat and a gate are disclosed. In one

aspect, a valve includes a gate having two discs spaced from one another, first and secondseats within first and second passageways of the valve, respectively, and at least onelever arm coupled to an actuator for rotating the gate, thereby diverting flow. The leverarm is disposed between the discs and pivotally couples to the gate such that thepivoting movement of the gate enables compensation for the misalignment. A methodincludes rotating a gate from a first position with a plane of the gate axially aligned withflow to a second position with the disc initially contacting a seat and compensating forthe misalignment by pivoting the gate with respect to the lever arm such that the gatesquarely contacts the seat.
