Abstract: A choke valve comprising: a body having an axial through hole and a radial entry port; a valve seat coaxially housed in the body axial through hole on a first side of the radial entry port; a pressure balanced valving member axially reciprocable within the body axial through hole between a first sealing position bearing against the valve seat and a second position spaced away from the seat; an actuator housing operably connected to the valving member; and a detachably connected reinforcement member detachably connected to the actuator housing and increasing the axial load that the actuator housing can take before failure of the actuator housing.
