1. A valve assembly, comprising:
a first and second valve, each of the first and second valves including a first port, a second port, a third port, and a flexure assembly, the flexure assembly is configured to move to and maintain a first position which causes the first port to open, a second position which causes the second port to open, and a third position which causes the first and second ports to close,
wherein at least a part of the flexure assembly is magnetisable, to provide a first magnet, a second magnet is associated with the first port and a third magnet is associated with the second port,
wherein one valve is configured to maintain a default failsafe position corresponding to the first position while the other valve transitions between the first, second, and third positions, and
wherein the one valve is configured to transition between the first, second, and third positions so as to act as a redundancy for the other valve in the event the other valve cannot transition between the first, second, and third positions.
