ORBITAL VALVE
ST 6301
aton Char-Lynn Valves:
230 CC Orbital
Displacement: 230CC/14.0 Cubic Inch
Flow Rate: 4.00-8.00 GPM
Load Circuit: Load Reaction
Mechanical Interface: Internal Involute Spline, 12 TOOTH 16/32 DP 30°
Fitting Size: 4X -6AN Fittings
All of the steering control valves offered by PSC are load reaction type. A load reaction valve allows physical axle forces to return the steering wheel to its original position when the operator releases the wheel after completing a turn. This return to center function is engineered to work in cross connected and balanced systems. It will work in a differential system, but not as well.
The displacement of the valve divided into the steering cylinder volume will determine the required turns of the steering wheel
lock-to-lock.

Orbital Plumbing
T- port = Return to Tank or reservoir
P port = pressure from pump
R port = pressure from the pump will be applied to this port when turning the steering to the right
L port = pressure from the pump will be applied to this port when turning the steering to the left
*with the growing popularity of gear driven pumps please make sure the rated flow of your pump at max RPM will work with the orbital you plan to purchase, if you have any questions or concerns or require a large orbital rated to flow 10+ GPM please contact us before purchasing
* damage to hydraulic components due to over pressurization, contamination, improper oil, incorrect install are not covered under warranty
