Abstract
A pressure control valve for a downhole drilling system includes a choke body and a restrictor body. The choke body is installed in the bore of a housing. A fluid flow flows through an orifice in the choke body. Changing a distance between the choke body and the restrictor body changes a pressure differential uphole of the pressure control valve.
