HydraForce | G3
Apresentando a HydraForce® G3 – A nova geração de alto desempenho e eficiencia das válvulas "Drop-In" projetadas especificamente para transmissão, motores diesel e aplicações de piloto remoto.

Desenvolvidas para alta performance nas condições mais severas e de altas temperaturas - Válvulas G3 operem com baixas amperagens, mantendo o mesmo ou melhor desempenho, comparados com conceitos convencionais.

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

    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.

  • PROPORTIONAL VALVE SERIES
    Flow ranges for G3 proportional 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.
