Гидрораспределитель 723-19-13501 для экскаватора Komatsu PC30 PC50 PC35MR PC40 PC50MR-2 PC30MR-2

Integrated design: The valve group integrates the main relief valve (Main Relief Valve), load holding valve and compensation valve. For PC-MR (short tail swing) models, these valve groups are structurally optimized to fit into compact space layouts.

Micro-operated performance: As part of Komatsu's CLSS (Closed Center Load Sensing System), this valve group is able to achieve "flow with load variation". This means that whether you're doing fine grading or digging at full capacity, the feel remains consistently smooth.

High responsiveness: Able to handle subtle pressure changes from the pilot system, ensuring millimeter-level excavation operations in narrow spaces.
