What Does This Relief Valve Mrv / Swing Motor / Travel Motor Do?
The main relief valve (MRV) limits maximum circuit pressure to protect the hydraulic system. Swing and travel motors convert hydraulic flow into rotary mechanical motion to drive the machine's upper structure rotation and undercarriage movement.

If your machine is showing any of the following, a faulty relief valve mrv / swing motor / travel motor may be the cause:
- Machine unable to swing or travel in one or both directions
- Weak or significantly reduced swing or travel speed under working load
