Directional and flow control valve and hydraulic system

A hydraulic system comprising:

• a directional and flow control valve including:
• a housing with a pump port, a first supply/discharge port, a second supply/discharge port, and a tank port, the housing including therein a first pilot chamber, a second pilot chamber, and a third pilot chamber;
• a first spool including a first end surface facing the first pilot chamber and a second end surface facing the third pilot chamber, wherein the first spool blocks the first supply/discharge port from both the pump port and the tank port, or brings the first supply/discharge port into communication with one of the pump port or the tank port;
• and
• a second spool independent of the first spool, the second spool including a first end surface facing the second pilot chamber and a second end surface facing the third pilot chamber, wherein the second spool blocks the second supply/discharge port from both the pump port and the tank port, or brings the second supply/discharge port into communication with the other one of the pump port or the tank port,
• a hydraulic pump connected to the pump port of the directional and flow control valve;
• a hydraulic actuator connected to the first supply/discharge port and the second supply/discharge port of the directional and flow control valve, wherein the hydraulic actuator moves in a first direction and a second direction;
• a first solenoid proportional valve that adjusts a pressure of the first pilot chamber of the directional and flow control valve;
• a second solenoid proportional valve that adjusts a pressure of the second pilot chamber of the directional and flow control valve;
• a third solenoid proportional valve that adjusts a pressure of the third pilot chamber of the directional and flow control valve;
• and
• control circuitry that controls the first solenoid proportional valve, the second solenoid proportional valve, and the third solenoid proportional valve.
