Diverter valve

A diverter valve (20) having a valve body with five ports (18,24,26,32,36). 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 (18,24) by travelling axially through a cylindrical diverter gate (118), and fluid flows between aligned third and fourth ports (26,32) by travelling axially through a generally cylindrical blocking gate. A fifth port (36) is blocked by a waste seal. When the diverter valve is in the second position, the fifth port (36) is open and a blocking projection (134) on the blocking gate (116) closes the fourth port (32). The blocking gate (116) and the diverter gate (118) direct fluid from the first port (18) to the third port (26), and from the second port (24) to the fifth port (36).
