As a crucial control component of the excavator's travel hydraulic system, this pilot valve stably maintains the hydraulic signal accuracy required for travel control, preventing malfunctions such as travel jamming and deviation caused by hydraulic signal fluctuations. Its reliable control performance protects core components such as the travel hydraulic motor and main control valve, reducing wear and tear on the hydraulic system caused by unstable pressure or control misalignment, and extending the service life of the travel system. This pilot valve is commonly used in Komatsu PC 200-8M0 and PC360-8MO excavators, and is one of the core components ensuring the normal and efficient operation of the travel function in these excavators.
