800164543 XCMG XS225JS road roller valve system spare parts

Short Description:

Valve system spare parts are core complete spare parts for road roller hydraulic control circuit, including multi‑way valve spools, valve seats, sealing kits, overflow valves, check valves and valve group connectors. They regulate hydraulic oil pressure, flow rate and direction to control vibration, travel and steering actions.

description

Part number: 800164543
Part name: valve system spare parts
Unit name: power system
Fit for XCMG road roller XS225JS, suitable for municipal road construction, subgrade backfill and site leveling compaction. Used to replace original valve system spare parts with spool wear, seal failure and valve jamming damage.

Internal component wear, seal aging and valve jamming will lead to insufficient pressure, slow response, joint oil leakage and weak output, directly reducing compaction efficiency.

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

advantages

Spool clearance, valve bore size and connector thread specification fully comply with original standard. Replacement without grinding and processing reduces assembly jamming risk.
Wear‑treated precision components withstand frequent hydraulic pressure alternating impact and adapt to frequent start‑stop operation of road roller.
Complete set of oil‑resistant and pressure‑resistant seals resist medium erosion, reduce internal and external leakage risk under alternating temperature and improve system stability.
Spare parts cover multiple vulnerable positions of valve assembly for convenient on‑site disassembly and inspection, cut downtime and meet stocking requirements for overseas projects in Middle East and Africa.

maintenance & replacement

Park machine on flat ground, fully release residual hydraulic pressure after shutdown before valve disassembly to avoid injury caused by high‑pressure oil spray.
Keep working area clean during disassembly, prevent sediment and metal debris entering valve cavity; block oil ports immediately after removal.
Clean all components before assembly, discard all old seals and reuse is forbidden. Tighten bolts evenly in diagonal sequence.
Perform no‑load trial run after assembly, test vibration and travel function item by item. Confirm zero leakage on valve joints before putting into operation.
Do not reuse after grinding repair when spool is scratched, valve bore is worn or valve body cracks, replace valve system spare parts directly.

warehouse

We have built four spare parts warehouses in Xuzhou, Jining, Kunshan and Changsha to provide customers from all over the world with a variety of high-quality spare parts. We can basically ship self-provided spare parts within three days after confirming the order. If the spare parts need to be adjusted or processed, they will be shipped within 7-30 days.
