sany sy215 control valve

Quick Answer The Kobelco SK200 / SK210 / SK220 / SK250 / SK260 excavators — the whole -8 generation plus the SK210-9 — share one family of main control valve assemblies, commonly ordered under two numbers: YN30V00101F5 and YN30V00126F1.

The PC300-8 control valve assembly — also called the main control valve or distribution valve — is the large, multi-section block that routes the main pump's oil to every function, sets priorities, limits system pressure and feeds the pump's control signal.

If the slow side follows the hoses, the problem is hydraulic (relief, cont...

Quick Answer The main control valve on a SANY SY205 or SY215 is the machine's traffic controller. The pump delivers one flow of oil; the valve decides which function gets it, how much, and in what order — boom, arm, bucket, swing or travel — and it also manages pressure and tells the pump how much output is needed. Everything happens through a set of precision-machined spools sliding i...
