Claim 18:
19. The system of claim 16, wherein:
a first net force exerted on the valve spool by the spring and detent system is opposed by a second net force exerted on the valve spool by the first and second electromagnetic coils;
the first net force is greater than the second net force to bias the valve spool to its first position when the first and second electromagnetic coils are de-energized;
the second net force is greater than the first net force to bias the valve spool in its second position when the first and second electromagnetic coils are energized;
the first net force is greater than the second net force when the valve spool is in its first position and either the first or second electromagnetic coil is energized; and
the second net force is greater than the first net force when the valve spool is in its second position and either the first or second electromagnetic coil is de-energized.
