A computer-implemented method and/or system for controlling a material handler comprises: processing, by an electronic control unit (ECU), a plurality of electronic input signals from at least one joystick; determining an adjustment for at least one of a pair of solenoids based on at least the plurality of electronic input signals from the joystick; controlling the pair of solenoids by the ECU and each solenoid acting in opposition to each of a pair of biasing elements of an open-center directional control valve to move the directional control valve to an extension position or a retraction position from a central position; determining a setpoint buildup pressure for a central passageway of the directional control valve; and actuating a constrictive solenoid of a pressure buildup valve to constrict the central passageway based on the setpoint buildup pressure whereby the constrictive passageway increases a pressure in the central passageway of the directional control valve.
