Universal Excavator Travel Relief Valve Compatible with Excavator

1. Product Overview & Wholesale Price Range

The Travel Relief Valve (man‑riding travel valve) is a special hydraulic pressure‑regulating spare part for excavator travel motor system. It limits and stabilizes travel circuit pressure, realizes man‑riding travel function. Common replacement symptoms include weak walking power, one‑side slow travel, uneven traveling speed and abnormal travel pressure value.

2. Application Scope

This Travel Relief Valve suits multiple excavator travel hydraulic maintenance and overhaul scenarios:

• Travel Motor Circuit Overhaul: Direct replacement for worn, stuck or damaged original travel relief valve assembly.
• Hydraulic Fault Repair: Solve weak walking force, unilateral slow travel, uneven traveling speed and pressure‑loss failures.
• Repair Workshop Usage: Strict dimensional tolerance, convenient installation, stable pressure‑control and man‑riding travel performance.
• Overseas Parts Reseller: Stable inventory supply, complete QC documents support cross‑border spare‑parts trading.

3. Common Travel Relief Valve Failure Troubleshooting

• Fault 1: Excavator Weak Walking Power & Slow Travel Speed
  Cause: Internal spool wear, spring fatigue, hydraulic impurity jamming valve core clearance.
  Solution: Install brand‑new Travel Relief Valve, flush hydraulic circuit and replace hydraulic filter element.
• Fault 2: One‑Side Slow Travel & Uneven Traveling Speed
  Cause: Valve‑core abrasion, pressure‑regulating spring performance degradation.
  Solution: Fit new Travel Relief Valve, fully clean the whole hydraulic oil circuit.
• Fault 3: Abnormal Travel Pressure & Unable To Realize Man‑Riding Travel
  Cause: Internal parts wear, oil passages blocked by hydraulic contamination.
  Solution: Replace complete travel relief valve assembly, inspect hydraulic oil cleanliness.
• Fault 4: Oil Leakage At Travel Relief Valve Mounting Surface
  Cause: Seal ring aging, mating surface scratch damage.
  Solution: Replace full travel relief valve assembly or matched seal repair kit.
