JAOF-1003 JAOF1003 Rotating Motor Relief Valve Safety Valve Pressure Relief Valve DH55 Excavator Construction Machinery Parts

Product Description

The GVO excavator relief valve, compatible with DH55 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 main relief valve for the DH55 excavator is a core plug-in pressure control valve within the distribution valve assembly. It plays a crucial role in limiting the pressure of the entire hydraulic system and providing overload relief protection. It directly determines the digging force, operational sensitivity, and operational reliability of the DH55 small excavator. 

The valve body is machined from high-quality alloy steel and undergoes quenching and tempering heat treatment. The valve body has high strength, can withstand high-pressure impacts, and is unlikely to deform even during long-term operation. The valve core and valve sleeve are precisely ground, and the valve ports are hardened and strengthened to resist oil erosion. They can resist wear caused by fine impurities in the hydraulic oil and reduce the probability of internal leakage of the valve ports. Special anti-fatigue springs are matched internally, which are compatible with the pressure parameters of the entire machine of DH55. After multiple pressure cycle tests, it is unlikely to experience weak springs, reduced elasticity, and ensures stable pressure output of the valve components. High-quality oil-resistant sealing parts are provided to adapt to high and low temperature conditions, effectively preventing oil leakage and dripping of the valve components, and eliminating pressure insufficient faults caused by sealing failure.
