Eaton Servo-Performance Proportional Directional Valve - 2

Introduction General Description Typical Section View 3 Spool Sleeve Details 5 AxisPro™ is a game changing machine control valve. Its embedded intelligence simplifies traditionally complex control practices. Plug and play design reduces machine build time, and its ability to predict potential maintenance issues increases machine reliability. AxisPro level 2 KBH valves, 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...

Eaton Servo-Performance Proportional Directional Valve - 3

General Description Unique benefits from AxisPro Built on the proven KBH servo Proportional Valve technology, Eaton’s new AxisPro Proportional Valve provides a range of controls capability in a modular design. These solenoid operated proportional valves offer high dynamic performance which enables them to be used in closed-loop control applications. The LED lens is standard on all AxisPro valves and provides a quick easy way to visually determine if AxisPro has detected any system warnings or faults. Detailed health, valve performance and warning/fault data is easily accessible via Eaton’s...
