ABSTRACT:
A diverter valve has a "Y" shape with a single inlet and two branch passageways formed at a confluence region of the "Y". A double sealing member paddle is pivoted on a shaft and located at the confluence of the two branches. The branches each have a replacement tapered seal seat. Rotation of the shaft in one direction forces one sealing member of the paddle onto one seat for full 360.degree. contact with the seat. Rotation of the shaft in the other direction forces the other sealing member of the paddle onto the other seat. A continuous peripheral seal contact is made with the seat. The seals and seats are concentric with the branch passageways and easily machineable and replaceable. The arrangement provides for smooth flow through the valve.
