White Drives 185 cc/ 11.3 c.i. Hydraulic Steering Control Orbital Valve - Load Reactive
FHV-CE185
The White Drive Products 185cc Hydraulic Steering Control Orbital Valve is a load reactive steering valve for full hydraulic systems that need responsive steering without moving to a larger-displacement orbital. With 185cc (11.3 cu. in.) displacement and a 4–8 GPM flow range, the FHV-CE185 is a strong choice for rock crawlers, off-road vehicles, and custom builds where steering speed and driver control need to stay balanced.
The load reactive circuit allows steering forces to feed back through the hydraulic system, helping the steering wheel return toward center after a turn. This design works best in balanced or cross-connected steering systems and can also be used in differential systems, although return-to-center response may be less effective. Four -6AN fittings are included for easier hydraulic system plumbing.

Fitment
Universal application for full hydraulic steering systems, including rock crawlers, off-road vehicles, and custom hydraulic steering builds.
Fitment Notes
- Works best with balanced or cross-connected hydraulic steering systems.
- Can be used in differential systems, but return-to-center performance may be less effective.
- Hydraulic steering system must support a 4–8 GPM flow range.
- System must be configured for a load reactive steering circuit.
- Orbital displacement should be matched to steering cylinder volume and the desired number of steering wheel turns lock-to-lock.
Tech Insight
1. What does the 185cc rating mean?
The 185cc displacement is the volume of hydraulic fluid the orbital moves per revolution of the steering wheel. Orbital displacement is one of the main factors that determines how many steering wheel turns are required to move the steering cylinder from lock to lock.
2. How does a 185cc orbital affect steering speed?
When used with the same steering cylinder, a smaller-displacement orbital generally requires more steering wheel turns than a larger-displacement valve. That can provide more steering resolution and make smaller steering corrections easier to control.
3. What is a load reactive orbital valve?
A load reactive orbital allows forces from the steering cylinder to feed back through the hydraulic circuit. In a properly configured system, this helps the steering wheel naturally move back toward center after completing a turn.
4. Can this orbital be used with a differential steering cylinder?
Yes. However, White Drive Products notes that load reactive operation works best in balanced or cross-connected systems. Return-to-center behavior may be less effective when the valve is used with a differential system.
5. How do I know if 185cc is the right orbital for my steering system?
The orbital should be selected around steering cylinder volume, desired lock-to-lock steering wheel turns, hydraulic pump flow, and vehicle use. The FHV-CE185 operates in the 4–8 GPM range, but cylinder size still plays a major role in determining the final steering ratio and response.
