Komatsu 206-60-51130 Rotary Solenoid Valve

The 206-60-51130 rotary solenoid valve is an electro-hydraulic component designed for Komatsu PC200-6 series excavators equipped with the 6D102 diesel engine. It regulates hydraulic fluid flow to the swing motor brake circuit, enabling controlled rotation locking during operation. The valve assembly features a steel housing with integrated coil, designed for direct mounting on the swing control valve block. Electrical connection uses a standard two-pin connector compatible with the machine's 12V DC system. The component operates as a normally closed valve, energizing to release the swing brake for rotation. Cross-referenced part numbers include 206-60-51131, 206-60-51132, and 20Y-60-32120. Installation requires verification of connector type and mounting orientation against the original valve marking.
