Abstract of the Disclosure A ball valve for use particularly in subsea hydrocarbon production systems including a valve body having a cavity of generally conical shape and communicating with inlet and outlet ports having a common axis. An insert assembly is provided with a valve ball, two ports corresponding to the inlet and outlet ports, respectively, and associated seat means. The insert assembly has a generally conical shape which is generally the same as that of the cavity and being adapted to be housed therein and to be retrieved therefrom. The insert assembly is composed of two parts joined together generally along a dividing plane. Connector means are provided for releasably fixing the insert assembly in the cavity, and actuator means are provided for rotating the valve ball about its axis between a closed and an open position with respect to said ports. The dividing plane between the two parts of the insert assembly is normal to the rotational axis of the valve ball and substantially coincides with the common axis of the inlet and outlet ports.
