SBX advanced steering valve

Designed to meet the demanding requirements of mobile equipment, the Eaton SBX advanced steering valve works in both electrohydraulic and steer-by-wire systems. The compact, modular valve increases flexibility and functionality when working with limited engine compartment space or when adopting electrical inputs into today’s steering solutions. The valve offers a range of redundancy options and can be paired with the OEM’s machine control system or an Eaton controller.

Full range of redundancy options

The SBX advanced steering valve can be mounted to a steering control unit in an electrohydraulic (EH) steering configuration, or to a secondary EH valve or manifold in a steer-by-wire (SbW) configuration, providing fail-operational functionality. It can also be provided as a standalone unit for use in steer-by-wire systems that do not require redundancy. This enables OEMs to provide a steer-by-wire system to one customer and an EH system to another without major changes in architecture. It also allows a simple transition from an orbitrol today to a backup valve in the future.

Flexibility that fits your machine design

  • Can be used in both steer-by-wire and electrohydraulic steering configurations
  • Pairs with an OEM’s machine control system or Eaton SFX or HFX controllers
  • Accommodates a range of redundancy requirements
  • Compact design enables remote mounting

Designed to comply with functional safety requirements

  • Isolation spool provides redundant EH shut-off capability, giving the orbitrol steering unit absolute priority at all times
  • Onboard electronic controller and redundant spool position sensor make precise flow control possible while enhancing diagnostic coverage

Powerful customization capabilities

  • Ideal for use with GPS-driven automatic navigation systems as well as additional inputs, such as a joystick, lever or alternative steering wheel
  • Enables customization of steering parameters, such as steering turn ratio, lock-to-lock wheel turns, steering knob position and steering feel
  • Enables the removal of the steering column in steer-by-wire configurations, which can improve operator sightlines, reduce noise in the cab, and permit rotation of the cab or seat without added steering inputs
