Patent ID: 10982787

Abstract:
In an actuated valve assembly, the valve includes a valve body defining a fluid passageway, an annular valve seat disposed on the valve body surrounding the fluid passageway, and a valve closing member movable between a closed position sealing against the valve seat and a fully open position spaced apart from the valve seat to permit flow. The actuator includes an actuator housing and an actuating mechanism movable within the actuator housing, by operation of the actuator, between a closing position in which the actuating mechanism holds the valve closing member in the closed position, and an opening position in which the actuating mechanism permits movement of the valve closing member toward the fully open position, the opening position being defined by engagement of the actuating mechanism with a stop portion of the actuator. The actuator is threadably adjustable on the valve to adjust a position of the actuator stop portion with respect to the valve seat, such that the opening position of the actuating mechanism may be selected to limit the valve closing member to a partial flow position between the fully open position and the closed position.
