Abstract: An on-off pilot stage valve arrangement for controlling at least one main stage valve. The on-off pilot stage valve arrangement includes a first pilot valve discretely operable between two states, an on and an off state, the first pilot valve having an input at which there is a first pressure and an output connected to the main stage valve, a second pilot valve discretely operable between two states, an on and an off state, the second pilot stage valve having an input at which there is a second pressure and an output connected to the main stage valve. Both the valves are configured to be set in one of the two states in case the arrangement loses power.
