Product Description


The GVO excavator relief valve, compatible with Hitachi excavators, is a key pressure control valve in the hydraulic system. It regulates hydraulic pressure, releases overload pressure, protects core hydraulic components such as the main valve and hydraulic pump, and ensures stable operation of the entire machine.


This relief valve is precision-machined from high-quality steel and undergoes overall quenching treatment. Equipped with oil-resistant and high-pressure-resistant seals, it boasts excellent sealing performance, impact resistance, and wear resistance. Suitable for the high-pressure hydraulic conditions of excavators, it effectively prevents internal leakage, pressure loss, operational instability, and vibration.

Product Introduction


The relief valve body is integrally forged from high-toughness alloy steel, eliminating the need for ordinary sand casting. This avoids inherent defects such as porosity, sand holes, and material looseness, allowing it to withstand continuous high-pressure impacts and machine vibrations under heavy-duty operation.

The valve core and seat, as key components subjected to long-term pressure bearing and reciprocating sliding, undergo a dual heat treatment process of quenching hardening and surface carburizing hardening. The surface hardness is sufficient to resist abrasive damage from mineral debris and metal impurities within the hydraulic oil, extending the service life of the components. The valve core mating area is precision-machined using high-precision mirror grinding equipment, accurately controlling the reasonable assembly clearance between the valve core and valve sleeve. This ensures smooth and sensitive valve core opening and resetting, effectively preventing malfunctions such as valve core jamming, pressure regulation failure, and return-to-position sticking.

The adjusting lock nut on the outside of the valve body is thickened and reinforced, ensuring even force distribution on the wrench during maintenance and disassembly, preventing slippage and edge chipping. Multiple sealing points are equipped with high-pressure, high-temperature, and oil-corrosion-resistant fluororubber O-rings, relying on multi-layer sealing to prevent iron filings and dust from entering the valve core cavity.


Packaging & Shipping


We use high-strength, environmentally friendly paper export packaging, which is reinforced, cushioned, and moisture-proof, suitable for long-distance international logistics transportation, and meets cross-border freight and environmental protection standards. International transportation adopts formal cross-border logistics, with full tracking of logistics information and supporting customs clearance documents to ensure smooth customs clearance and timely delivery of goods overseas.
