Description

 

The relief valve assembly within a swing/turning motor protects the hydraulic motor and swing mechanism from excessive pressure.

It typically contains two cross-port relief valves—one for clockwise rotation and one for counter-clockwise rotation. If swing pressure exceeds the preset limit, the relevant valve opens and redirects oil from the high-pressure side to the low-pressure side. This:

  • Limits maximum swing torque.
  • Absorbs pressure spikes when starting or stopping.
  • Provides smoother deceleration and reduces shock loading.
  • Protects the motor, hoses, seals, swing gearbox and structure.
  • Helps prevent cavitation by supplying make-up oil to the low-pressure side.
