Abstract
An angled or inline choke for flowing drilling fluid to a choke and kill manifold, wherein the choke has a body with a bore, a connection can be sealed to the body and can have a connection bore in communication with the bore. A locking plate can index the connection to the body. The choke can have a cavity with a piston. A port can be in communication with the cavity to provide a hydraulic fluid to the piston. A choke bean in the bore can flow drilling fluid to the choke and kill manifold. A tip can connect to the choke bean with a rod. When the hydraulic fluid passes into the port, the piston can move within the bore and compress a choke element around the tip to cause restriction of the drilling fluid, enabling for control of a pressure of the drilling fluid.
