Split flow valve arrangement

A split flow valve arrangement comprising a first valve portion (38) having an inlet (60), a first outlet (64) and a second outlet (66); and a second valve portion (40) having a first inlet (80) coupled to the first outlet (64), a second inlet (82) coupled to the second outlet (66), a main outlet (84) and a secondary outlet (86). The inlet is selectively coupled to none, one or both of the first and second outlets (64,66); the first inlet is selectively coupled to the main outlet and the second inlet is selectively coupled to the secondary outlet. The first and second valve portions (38,40) are constrained to move in synchronicity to therefore selectively direct fluid to flow from the inlet to none, one or both of the main and secondary outlets (84,86).
