 Key attributes

Precision Overload Protection

The primary function of these relief valves is to provide fast and accurate overload protection for the hydraulic swing circuit. When a sudden pressure spike occurs, the valve instantly opens to relieve excess pressure, preventing damage to the swing motor, hydraulic pump, and other critical components.

Maintains Stable System Performance

By precisely limiting the maximum pressure in the swing circuit, these valves help maintain stable and consistent hydraulic performance. The relief valve setting helps ensure predictable and responsive machine control during demanding dozing operations.

Engineered for Durability & Long Service Life

Manufactured to Komatsu's original equipment specifications, these valves are built with high-quality materials to withstand the extreme pressures and harsh conditions typical of heavy earthmoving applications. They are designed for reliable, long-lasting service with minimal maintenance.
