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). In a variety of embodiments the turning component (12) additionally services as the valve seat (13), and as a behind the seat seal (16). Sealing member embodiments include floating and trunnion-mounted ball and partial ball valves, and butterfly valves. The preferred embodiment of butterfly valve has a removable resilient seal material (71) such as PTFE or a graphite-based laminate, retained to the valve disc member (11) to facilitate complete repair of all flow isolation surfaces without having to remove the disc member from the valve through the access port (50). Method for removing and installing valve internals through the access port is disclosed.

A method of repairing a valve with a rotating member for use in controlling fluid flow in a pipeline having a fluid flow path from an upstream pipeline segment to a downstream pipeline segment, wherein said upstream pipeline segment and said downstream pipeline segment have a common flow axis displaced by said valve, and wherein said valve comprises: a inlet flow passageway in fluid communication with said upstream pipeline segment, and wherein said inlet flow passageway comprises: an initial portion having a flow axis generally coextensive with the common flow axes of said upstream and downstream pipeline segments; and, a final portion having a flow axis which forms an obtuse angle with the direction of fluid flow from the upstream pipeline segment to the downstream pipeline segment along the common flow axes of said upstream and downstream pipeline segments; an outlet flow passageway in fluid communication with said downstream pipeline segment, and wherein said outlet flow passageway comprises: an initial portion having a flow axis which forms an acute angle with the direction of fluid flow from the upstream pipeline segment to the downstream pipeline segment along the common flow axes of said upstream and downstream pipeline segments; and, a final portion having a flow axis generally coextensive with the flow axes of said upstream and downstream pipeline segments; and, a valve body intermediate said inlet flow passageway and said outlet flow passageway, said valve body comprising: a chamber having an axis generally coextensive with said final portion of said inlet flow passageway, and providing a housing for a rotating valve member and a removable valve body chamber component disposed therein; a rotating valve member capable of fluid flow control; a valve maintenance access port positioned at one end of said chamber, downstream of said rotating valve member; and, said removable valve body chamber component intermediate said rotating valve member and said valve maintenance access port for sealingly engaging one end of said rotating valve member and the other end sealingly engaging a surface of said chamber adjacent said access port when fully inserted within said valve body chamber through said maintenance access port comprising: an inlet portion flow passageway having a flow axis generally coextensive with the flow axis of said final portion of said inlet flow passageway; and, an outlet portion flow passageway having a flow axis generally coextensive with the flow axis of said initial portion of said outlet flow passageway; and wherein maintenance of said rotating valve member and said removable valve body chamber component can be effected by way of said maintenance access port, which method comprises: a. opening of said valve maintenance access port; b. removal of said removable valve body chamber component; c. inspection of said rotating valve member and said removable valve body chamber component; d. maintenance of said valve, including repair and replacement of said rotating valve member and said removable valve body chamber component, as necessary; e. realignment of said rotating valve member and replacement of a removable flow passageway component; and, f. closing of said valve maintenance access port.
