GVO 61029693 KMX15RB B45201 Hydraulic Hold Valve Control Valve Balance Valve SY205 Excavator Construction Machinery Parts

Product Description

The GVO excavator relief valve, compatible with SY205 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 valve body of the overflow valve is made by casting high-strength ductile iron as a single piece. The raw material is fully treated with aging to relieve internal stress, eliminating the risk of deformation and cracking of the valve body under long-term pressure-bearing and continuous vibration conditions. The oil passage of the valve body and the installation mating surface are processed by precise CNC technology, with high flatness accuracy. After assembly, the seal is tightly fitted, eliminating the problem of oil leakage and dripping from the valve surface. 

The internal valve core and valve sleeve are made of high-quality alloy steel. They undergo quenching and tempering heat treatment and high-precision mirror surface grinding processing. The mating clearance between the valve core and the valve sleeve is precisely controlled, providing extremely strong wear resistance. It can resist the erosion and wear caused by impurities in the hydraulic oil. Even in harsh working conditions such as large dust on the construction site and limited cleanliness of the hydraulic oil, it can still maintain stable sealing effect for long-term cyclic operation. 

The pressure regulating spring inside the valve is made of high elasticity alloy spring steel. It has outstanding fatigue resistance and will not show elastic attenuation under high-frequency pressure alternating impact during excavator operation. It has stable pressure setting value over a long period of use and will not experience pressure drift, malfunction or other common faults of auxiliary components.
