Brake valve basics

Eaton brake valves are available in power, manual and hybrid styles with single or double spools. Double-spool brake valves feature two identical valves mounted together in the same casting, which can be used together or separately for brake-assisted turning. Eaton brake valves function in two modes: power and manual backup. In power mode, the valve operates like a pressure-reducing valve. In manual mode, the valve operates as a two-stage pump for increased system safety.

Achieve the perfect feel

Braking systems are less about specifications and more about “feel” for the operator. At Eaton, we work closely with OEMs to understand what they’re looking for in a braking system, then design a solution to match. We fit the valve to the application, not the other way around.

Increase machine performance and operator productivity

Get the system you want without sacrificing performance. Depending on valve type, Eaton brake valves can:

  • Increase safety through emergency backup capability, which seamlessly transfers from powered to manual braking with no change in pedal effort
  • Reduce costs by eliminating the need for accumulators, charging valves and associated plumbing and electronics
  • Increase efficiency through elimination of accumulators
  • Reduce braking force with powered valves
  • Enable actuation with separate left and right brake pedals for differential braking or with one pedal for both sides
  • Improve straight-line braking in dual-pedal applications through a built-in balancing feature
  • Ease installation through flange mounting and a self-bleeding function
