A drum is rotatably located in the housing and includes one or more fluid pathways to convey fluid flow between the inlet and the outlet. The rotary valve further includes a single-piece unitary drum seal having a portion located around a perimeter of a port of the one or more fluid pathways to seal between the drum and the housing. A drum seal assembly for a rotary valve includes a single piece, unitary drum seal disposed at a drum of the rotary valve. The drum seal has a portion extending around a perimeter of a port of one or more fluid pathways of the drum to seal between the drum and an inner wall of a housing. The drum seal assembly further includes an energizer to urge the drum seal into contact with the housing.
