A control valve for a hydraulic machine steering system includes a valve body defining a first actuator port, a second actuator port, a tank port, a pump port, and a manual steering interface. A directional control spool is disposed within the valve body to selectively couple the first actuator port, the second actuator port, the tank port, and the pump port. Further, an isolation spool is disposed within the valve body to selectively couple the directional control spool to each of the first actuator port, the second actuator port, and the pump port, and to selectively couple the pump port to the manual steering interface.

    一种用于液压机转向系统的控制阀,包括限定第一致动器端口、第二致动器端口、储罐端口、泵端口和手动转向接口的阀体。方向控制阀芯设置在阀体内,以选择性地联接第一致动器端口、第二致动器端口、储罐端口和泵端口。此外,隔离阀芯设置在阀体内,以将方向控制阀芯选择性地联接到第一致动器端口、第二致动器端口和泵端口中的每一个,并且将泵端口选择性地联接到手动转向接口。
