Eaton Servo-Performance Proportional Directional Valve - 2

AxisPro level 1 valves,such as KBS1-5 (ISO size 5),can be used to control machine motions in open loop or closed loop control applications.The valve receives its analog command input on the 7-pin,main,connector from an external axis control device. AxisPro level 2 or level 5 valves, such as KBS2-5(or KBS3-5 with sensors),can be used to control machine motion in open or closed loop control applications.The valve can receive its analog command input on the 7-pin connector from an external axis control device or,with the available on-board motion control feature activated (via Eaton Pro-FX...
