EHi inline electrohydraulic steering valves
The EHi is an electrohydraulic steering valve suitable for steer-by-wire, autonomous, and all-wheel steering systems with pressures up to 280 bar [4,060 psi] and flows up to 70 l/min [18.5 US gal/min]. It provides design flexibility when used with joystick or electric steering wheel input devices, and compatibility with proven technology ensures repeatable high performance and precision.
Features and benefits (OEMs)
- Increased machine and cabin design flexibility with latest steer-by-wire technology
- Integrated safety and steering controller with interface to auto guidance (GPS), joystick, and electric steering wheel
- Proven technology that accelerates time to market
- Compliant with all current legislation and safety standards including SIL 2, AgPLd, and Cat 3
- Allows combination of orbitrol steering for steer by wire
- Integrated priority valve
- Electric or hydraulic disengage of electrohydraulic steering (e.g., auto guidance)
Applications
- Agriculture
- Construction
- Road building
- Autonomous vehicles
