GVO JAOF1003 JAOF-1003 Rotary Motor Relief Valve Safety Valve Pressure Relief Valve DH55 DH60-7 Excavator Mechanical Parts

Product Description

The GVO excavator relief valve, compatible with DH55 DH60-7 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

This type of relief valve is a core hydraulic safety component specifically designed for the distribution valves of DH55 and DH60-7 small-sized excavators. It is also compatible with multiple models of the same platform. In the hydraulic circuit of the entire machine, it performs the key functions of pressure limitation, overload protection, and pressure stabilization. It is the core component that ensures the digging power, smoothness of actions, and safe operation of hydraulic components of the entire machine. 

The valve body is entirely manufactured from high-strength alloy steel. The valve core and valve sleeve have undergone precise honing treatment, and are combined with high-precision grinding sealing surfaces. It can withstand high-frequency and high-pressure hydraulic oil impact, effectively resisting the erosion caused by fine impurities in the hydraulic oil, significantly reducing the risks of valve core sticking and sealing surface abrasion and pressure leakage. The entire set of components is equipped with high-quality sealing rings that are resistant to high and low temperatures and anti-hydraulic oil corrosion. In various changing working conditions such as high-temperature operation in summer and cold machine startup in winter, the sealing rings can maintain good sealing performance, reduce internal leakage and seepage problems, and avoid system pressure loss caused by aging of sealing components. This solves common fault points such as weak engine heat-up and slow actions.
