Description

ABSTRACT:
The present invention is directed to rotary valve assemblies and, more particularly, to a rotary valve assembly for use in an oil and gas production system. The valve assembly comprises a movable actuator sleeve movable in response to hydraulic pressure and at least one seat, the at least one seat having at least one fluid channel capable of providing fluid flow therethrough. The valve assembly also comprises a rotating disk disposed between the at least one seat and a support bushing, the rotating disk capable of rotating in response to movement of the movable actuator sleeve, the rotating disk having an open position and a closed position, wherein the open position permits fluid flow through the at least one fluid channel of the at least one seat and the closed position stops fluid flow through the at least one fluid channel of the at least one seat.
