description

Part number: 803009793
Part name: valve group
Unit name: rear anti-collision frame assembly
Applicable Models: XCMG XS185 vibratory road roller

Valve group is the core component of road roller hydraulic control system. Integrated with multiple valve slices, it controls on‑off status, pressure and flow of vibration, steering and travel oil circuits, distributes hydraulic oil to each actuator, and ensures stable output of travel and compaction functions. Worn valve slice, stuck spool and aged seals will lead to slow response, insufficient pressure, internal leakage and abnormal noise, and directly impair compaction performance.

=======================================

advantages

Port layout, flow path size and relief pressure comply with original standard, excellent interchangeability for direct installation without pipeline modification.
Precisely machined spool with reasonable fitting clearance reduces internal leakage, delivers stable pressure and resists hydraulic impact.
Oil‑resistant and temperature‑resistant sealing assembly adapts high‑frequency alternating load of road roller and lowers leakage failure risk.
Integrated assembly reduces on‑site commissioning work for easy maintenance, convenient for overseas project spare‑parts stocking.

FAQ

Q: Can valve group with slight internal leakage keep working?
A: Internal leakage will deteriorate gradually and cause weak vibration and travel slipping, timely replacement is recommended.
Q: Why pressure is still insufficient after valve group replacement?
A: Check seal installation condition, inspect hydraulic pump output pressure and confirm no pipeline blockage.
