Combined movements that turn slow, a machine that drifts with the levers centred, or oil that runs hot can all point to a worn KMX15YC / KMX15R / SG25 Excavator Main Control Valve. Spool and bore wear lets high-pressure oil cross-leak between circuits. RITO supplies this KMX15YC / KMX15R / SG25 Excavator Main Control Valve for the 20-25 ton class excavator range to restore precise simultaneous control.

In StockKMX15YC / KMX15R / SG25 Excavator Main Control Valve for the 20-25 ton class excavator range, rated at 15 series nominal displacement. The valve distributes pump flow to the boom, arm, bucket, swing and travel circuits while holding pressure accuracy and simultaneous-operation balance, and its spool clearances and relief settings determine how the whole machine behaves. Section and spool wear is the usual reason combined movements slow down and the oil runs hot. Known designations include KMX15YC / KMX15R / SG25. RITO supplies it as a direct-fit service replacement; confirm the machine model, bolt pattern, port positions and control linkage against the removed valve before ordering.

Matched spools and bores let the {M} distribute pump flow evenly between boom, arm, bucket, swing and travel, keeping combined movements smooth and predictable.
Main relief and section relief settings hold pressure where the machine specification expects it, so breakout force and travel performance stay consistent under load.
The {M} keeps the original bolt pattern, port positions and linkage arrangement, allowing a straightforward replacement without modifying the machine.
Tight spool fits cut the internal leakage that makes circuits drift and hydraulic oil run hot, protecting pumps, seals and cylinders downstream.
FAQ
Q: Which excavators use the {M} control valve?
A: The {M} is a Kawasaki KMX series main control valve used in the {cls} excavator sector. Valve sections and spool arrangements differ between machine variants, so confirm the machine model, bolt pattern, port layout and linkage against the valve being replaced.
Q: What are the common reference numbers for {M}?
A: Service identifications include {REFS}. The valve nameplate together with the machine serial number gives the most reliable confirmation of identity.
Q: What symptoms show the {M} control valve is worn?
A: Watch for slow or uneven combined movements, drifting circuits with the levers centred, loss of fine control, weak travel or boom priority, and hydraulic oil that runs hotter than usual.
Q: Is the {M} a control valve or a pump?
A: The {M} shown here is an excavator main control valve. It is not a hydraulic pump or a swing motor, and it is supplied as a complete valve assembly.
Q: How do I confirm the {M} fits my machine?
A: Compare the mounting bolt pattern, the number and position of the ports, the control linkage arrangement and the relief valve settings with the removed valve. All four must match before ordering.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
