Product profile
Precise Negative Flow Control – As a negative feedback relief valve, it senses pressure changes in the neutral return circuit and creates a negative feedback signal to automatically adjust main pump displacement. When no operation is performed, system pressure rises, and the feedback signal reduces pump displacement to minimum, significantly lowering energy loss and system heat generation for idle fuel savings.
Swing Priority Function – During combined operations of swing with boom or arm, the valve prioritizes hydraulic flow to the swing motor. This prevents oil from flowing excessively to low-pressure actuators and ensures coordinated, responsive compound movements.
Pressure Balance & Overload Protection – The valve provides pressure balance and quickly relieves system overpressure, preventing hydraulic components from damage due to overload and ensuring safe, stable operation.
