A valve includes housing and body members that have cylindrical valve surfaces. The valve body being centered in the housing by an array of at least three resilient support elements circumferentially spaced about the valve body. The valve body includes a plurality of ports arranged for selective alignment with housing ports as the valve body member is rotated and a through passage that connects two of the valve body ports. The resilient support members are apertured and conform in sealing engagement between the juxtaposed cylindrical valve surfaces so that they also function as annular valve seal members.
