Abstract
A choke gate valve includes a housing that defines a fluid bore and a gate with multiple throttling orifices. The gate is configured to move within the housing between a first throttle position in which the gate extends across the fluid bore to position a first throttling orifice of the multiple throttling orifices in the fluid bore to throttle a fluid flow through the fluid bore and a second throttle position in which the gate extends across the fluid bore to position a second throttling orifice of the multiple throttling orifices in the fluid bore to throttle the fluid flow through the fluid bore.
