1 - Voltage not applied yet, valve in output state
2 - Exponential voltage increase, magnetic field is built up, increase of the spring preload force
3 - Valve starts to move, spring force increases, valve reaches end position
4 - Exponential voltage increase, current limitation through self-induction of the coil
