Zusammenfassung:	A system includes a choke valve coupled to a Christmas tree on a wellhead. A smart module may be coupled to the choke valve. A hydraulic control unit may be coupled to the smart module and the choke valve. The hydraulic control unit hydraulically actuates the choke valve. A first sensor may be attached upstream of the choke valve and a second sensor may be attached downstream of the choke valve. The first sensor measures an upstream pressure and the second sensor measures a downstream pressure. A controller may be coupled to the smart module and the hydraulic control unit. The smart module receives the upstream pressure, the downstream pressure, and well data to generate commands to adjust a choke size of the choke valve corresponding with a required production rate of a well. The controller may manage a transmission of hydraulic pressure from the hydraulic control unit to actuate the choke valve based on the generated commands.
