Hitachi excavator accessory 0828301 distribution valve overflow valve (main gun)

Hitachi excavator 0828301 distribution valve relief valve (distribution valve main relief valve/main gun) is designed to provide precise pressure relief protection for hydraulic distribution valves (main control valves) of small and medium-sized excavators such as ZX70, ZX75UR, ZX80LCK, ZX85US-HCME, etc. Adopting high-strength castings, high-precision valve cores, rubber sealing rings, and pressure resistant metal shells, with a set pressure of about 32-36MPa, it has sensitive response, pollution resistance, corrosion resistance, and vibration resistance. Perfectly solves common faults such as walking weakness, continuous increase in hydraulic oil temperature and water temperature, vehicle holding, insufficient power, decreased operating power, and rotation overload, directly ensuring the high-pressure stable operation of the walking motor and arm/rod/rotating mechanism.
