OEM

  • Original Equipment Manufacturer

  • A company that produces hardware components or complete systems that are integrated into another manufacturer's product.

OEM7

PPP

PVED

  • Proportional Valve Electronic Driver

  • A Danfoss electrohydraulic steering valve and its integrated electronic driver that controls hydraulic flow proportionally to steer agricultural machinery.

PVED-CL

  • Proportional Valve Electronic Driver — Closed Loop

  • An electrohydraulic steering valve with integrated closed-loop control electronics. It receives steering commands and uses real-time feedback to accurately control the hydraulic steering actuator.

PVED-CLS

  • Proportional Valve Electronic Driver — Closed Loop Steering

  • A Danfoss PVED variant that implements closed-loop steering control, continuously comparing the commanded and actual steering angle to minimise tracking error.

PVES

  • Proportional Valve Electronic Steering

  • An electrohydraulic steering valve variant used in automatic steering systems, similar in function to PVED. It controls hydraulic flow proportionally to execute steering commands from the guidance system.
