Abstract
A diverter valve having a valve body with five ports. A valve assembly is disposed in the valve body and is rotatable between first and second positions. When the valve assembly is in the first position, fluid flows between aligned first and second ports by travelling axially through a cylindrical diverter gate, and fluid flows between aligned third and fourth ports by travelling axially through a generally cylindrical blocking gate. A fifth port is blocked by a waste seal. When the diverter valve is in the second position, the fifth port is open and a blocking projection on the blocking gate closes the fourth port. The blocking gate and the diverter gate direct fluid from the first port to the third port, and from the second port to the fifth port.
