Smooth, precision steering keeps operators in control

The Series 25 steering control unit provides one of the smoothest steering experiences you’ll find. Features include:

  • Balanced architecture and thicker sleeve design increases reliability and provides smooth performance, even under transient pressure and thermal conditions
  • Symmetrical valving increases balance for precise servo response and uniform steering action, while progressive valving reduces operating costs
  • Seal and centering spring designs provide positive, low-effort steering for excellent vehicle control
  • Optional Q-Amp and wide angle technology maximize steering control

Engineered for demanding applications

More compact and cost competitive than other higher-flow steering solutions, the Series 25 steering control unit offers a number of design efficiencies:

  • Optional pilot pressure port can be used for diagnostics or increased priority valve flow
  • High-grade ductile iron housing provides increased strength for demanding applications
  • High-capacity gerotor provides ample fluid displacement in a compact package
  • Load-sensing, open-center and closed-center designs provide greater design flexibility
  • Integrated valves and load-sensing capabilities match performance to load requirements
  • Responsive, reliable and cost-effective solution compared to multi-valve pilot steering systems
