Critical System Protection
Prevents Overpressure Damage: The relief valve limits hydraulic pressure in the left and right swing circuits to a safe, pre-set level. This protects the motor, pump, and other components from catastrophic failure due to pressure spikes.
Prevents Cavitation: The integrated check (makeup) valve supplies oil to the motor's inlet when a vacuum is created during sudden stops. This prevents cavitation, which can cause severe damage to internal components.
