Hitachi ZX110 relief valve – Product Details
This new Hitachi ZX110 relief valve (part number 4446002) is a replacement part for the Hitachi ZX110 excavator. The relief valve is a hydraulic relief valve that limits circuit pressure and protects the system from overload. It is made to match the original Hitachi part number 4446002 for a direct fit.
A faulty relief valve causes low power, overheating and pressure spikes. Fitting a new ZX110 relief valve restores full performance on the Hitachi ZX110 excavator and helps avoid costly downtime on site. Always check the part number 4446002 against your machine’s parts book or the old part before ordering.
