Abstract: Straight line flow rotary valves with the valve member flow passage (21) turned away from the pipeline flow axis (22), to dispose the valve internals to an access port (50) located downstream on the same flow axis of the valve member (11). Another embodiment is used in place of pipe elbows where the rotary valve internals are accessed through a port (50) on the same flow axis (22) as the upstream pipe. In both valve body embodiments, the flow is turned again, downstream of the valve member (11), to communicate with the connecting downstream piping which, in the first embodiment is along the same axis as the upstream pipe (22), and in the second embodiment, is on a different axis (39), and, is generally 45 or 90 degrees turned from the upstream pipe.In both embodiments the flow turns in a component (12) installed, through the body access port (50). In all embodiments the turning component also services as the pressure boundary access cover over the body opening (50).
