Kobelco SK200-8 · Valve Assembly,Control · 11 part numbers

Illustration reproduced from the Kobelco SK200-8 parts catalogue for part identification only. Callout numbers on the drawing match the Ref. column in the table below. Kobelco is a trademark of its respective owner; Shenyue Machinery is an independent supplier of excavator parts.
The Valve Assembly,Control group on the Kobelco SK200-8 contains 11 separately orderable part numbers. The Ref. column mirrors the callout numbers on the illustration, so a part can be ordered straight from the drawing. The list comes straight from the Kobelco SK200-8 catalogue for this machine family.

Part numbers as fitted to the Kobelco SK200-8 excavator. Where a position changed during the production run, the serial number settles which one applies to your machine.
Structurally, these 11 numbers fall into 6 Kobelco number series — YN30V, ZS23C, ZD12G among the largest. In practice that means repeated items such as capscrew, valve, ring and 4 hardware positions.
The high-quantity positions are: ZS23C12105 (capscrew, ×3 per assembly); ZS23C10025 (capscrew, ×2 per assembly); YX35V00002S171 (capscrew, ×2 per assembly). The full list follows below.
Rebuild-at-component-level is the practical route for most Kobelco SK200-8 hydraulic assemblies. Wear shows up at predictable points — spool clearances, valve plates, bearing sets, seal packages — and those items are listed individually, so you can quote only what is worn instead of exchanging the complete unit.
Seal kits for this group are quoted from the same table — the O-ring and seal positions carry their own numbers, so a hydraulic repair never forces a purchase at assembly level.
Usually yes — the callout numbers on the drawing map directly to the Ref. column in the table. If your machine differs by serial range, send a photo of the part and we will confirm before quoting. If that matches your case, quote ZS23C12105 and we will take it from there.
Yes — send the serial and the part number together; where a position changed across the run we flag it and quote the number that matches your build.
Yes. Send the Kobelco SK200-8 serial number with the part number and we confirm the fit from the serial range. Where a component changed during the production run, we flag it before you commit.
