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 Functions

1. Pressure Protection: Limits the maximum pressure of the hydraulic system, preventing damage to pipelines, pumps, and distribution valves due to overload.

2. Overload Pressure Relief: Automatically relieves pressure when digging resistance is too high, protecting actuators such as the boom, stick, and travel motor.

3. Pressure Stabilization: Maintains the set working pressure of the hydraulic circuit, ensuring stable digging force output. Hydraulic Breaker Compatibility: Some models can be used as overload safety valves in hydraulic breaker circuits.
