HydraForce | G3
Introducing HydraForce® G3 – A new generation of remarkably efficient, high performance, 'drop-in' cartridge valves designed specifically for powertrain, diesel engine and pilot control applications.

Engineered to perform flawlessly in the harshest, high-temperature conditions – G3 valves operate at significantly lower amperages while delivering the same or better performance as conventional designs.

G3 offers five compelling advantages for your applications:
  • Precise linear control with low hysteresis
  • Higher on/off force levels for maximum flow capacity
  • Responsive in low-temperature conditions
  • Proportional current draw reduced by 30%
  • Lower pull-in voltage on solenoid product
We're here to help
Our application engineering team is ready to specify the optimal solution for your machine.

    APPLICATIONS —
    G3 valves can be used on many types of hydraulically powered equipment:

    Transmissions — Clutch engage, 4WD, Diff Lock, Park Brake, Pressure Regulation

    Pilot Controls — Spool piloting, switching, directional control, function disable

    Engine Controls Recirculation, Pressure Regulationn

    Also... Low pressure fan drives, pilot pressure control of logic element



    G3_applications
  • ON/OFF VALVE SERIES
    MODEL SV

    Flow ranges for G3 ON/OFF valves serve different market segments. The lower flow valves can be used in piloting circuits while the higher flow valves can be used in directional control or other applications. With top-mounted solenoid coils, compact G3 valves can be spaced tighter. Top-mounting makes it easier to attach wiring harnesses.

    — Continuous duty pull-in at 120°C and 75% of nominal coil
         voltage

        • New class of operation
        • In lower temperature environment
        • increased flow rating
    — Improved pressure drop
    — Improved response times
        • On-time reduced from 50ms to below 25ms
        • From higher actuator forces & smaller armature
    — Flange mount allows connector to be rotated in any orientation

    — Higher actuator force with smaller valve armature improves
         cold temperature response and contamination resistance.
