  • Wellhead assembly with an annulus access valve
    Patent number: 9611717
    Abstract: A wellhead assembly includes an annulus access valve (AAV) disposed in a wellhead hanger. Upper and lower annulus access bores intersect the bore at upper and lower ports. The AAV includes a body that reciprocates within the bore between open and closed positions. Hydraulic fluid moves the body between the open and closed positions. Axially spaced apart upper and lower apertures are formed through the body outer surface allow communication to a chamber within the body. When in the open position, the upper and lower apertures respectively register with the inlet and outlet ports so that the upper and lower annulus access bores are in communication through the AAV. When in the closed position, a solid portion of the body registers with one of the inlet or outlet ports, thereby blocking communication through the AAV between the upper and lower annulus access bores.
