A hydraulic circuit includes: a priority valve including a first position and a second position where: the first position includes a first fluid passage and a fixed bypass orifice connected to the first fluid passage; the second position includes a second fluid passage and a variable bypass orifice connected to the second fluid passage. The hydraulic circuit further includes: a first fluid line fluidly connecting the priority valve and a first machine component; a second fluid line fluidly connecting the priority valve and a second machine component; a check valve placed between the priority valve and the second machine component and fluidly connecting the priority valve and the second machine component; an oil passage on the priority valve fluidly connected to one or more machine components other than the first and second machine components; one or more actuators connected to the priority valve; and a control valve communicatively connected to the one or more actuators connected to the priority valve.
