The pilot pressure control assembly further includes a first pilot valve assembly and a second pilot valve assembly. Each one of the first and second pilot valve assemblies are individually controllable so as to selectively provide a first fluid flow direction from a pressure line to the pilot outlet and a second fluid flow direction from the pilot outlet to a drain line. At least the first pilot valve assembly is adapted to assume a maximum pressure supply condition so as to supply a first pilot valve assembly maximum pressure to the pilot outlet. At least the second pilot valve assembly is adapted to provide a pressure drop from the pilot outlet to the drain line via the second pilot valve assembly. The pilot pressure control system is configured such that when the pilot pressure control system is connected to the pressure and drain lines and W hen the first pilot valve assembly is controlled so as to assume the maximum pressure supply condition and the second pilot valve assembly provides a fluid flow in the second fluid direction with a minimum pressure drop, the pressure at the pilot outlet is equal to or above 20 of the first pilot valve assembly maximum pressure (Pmax).
