Abstract
A flow valve that provides for control of a fluid flow rate utilizing a first open position and a second open position. Various embodiments of a flow valve having an inlet, an outlet, and a passageway therebetween are provided that comprise a damper element pivotally arranged within the passageway that is movable between a first position in which fluid flow through the passageway is substantially unaffected by the damper element, and at least a second position in which fluid flow through the passageway is substantially reduced by the damper element. An adjustable stop is further provided for adjustably limiting the movement of the damper element to establish the second position of the damper. A moveable operator is provided for moving the damper element between the first position and second position.
