电磁阀和歧管位于右机架梁上中央支撑的内侧。 来自转向泵的油通过软管 (10) 进入电磁阀和歧管。 电磁阀和歧管首先给予转向系统优先权。 电磁阀 (4) 保持关闭，直到转向系统达到正确压力。 一旦满足转向系统的要求，则电磁阀 (4) 打开。 当电磁阀 (4) 打开时，油流入连接在电磁阀和歧管上的其他系统。 电磁阀和歧管还包含一个单向阀 (2) ，这个单向阀会在没有来自转向泵的流量时维持转向系统中的压力。 这使得转向蓄能器可以在发动机故障或转向泵故障时维持转向压力。
连接在电磁阀和歧管上的其他系统包含后桥冷却风扇的齿轮马达、后桥润滑的泵和马达、制动器冷却的马达和泵的马达。 当电磁阀 (4) 通电时，控制阀 (3) 控制流入后桥冷却风扇的齿轮马达、后桥润滑的泵和马达以及制动器冷却的马达和泵的流量。
转向泵压力和流量补偿阀固定于转向活塞泵上。 转向泵压力和流量补偿阀决定转向活塞泵的旋转斜盘角度。 安全阀 (7) 用作转向系统的安全阀。
