GVO K9000945 J98A2021 420-00122 Pressure Relief Valve Rotating Valve Safety Valve DX DH300 DH370-7 SH300A3 SH460 Excavator Parts

Product Description

The GVO excavator relief valve, compatible with DX DH300 DH370-7 SH300A3 SH460 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 overflow valve is specifically developed for the hydraulic systems of DX, DH300, DH370-7, as well as Sumitomo SH300A3 and SH460 excavators. It is a core pressure protection accessory for the distribution valve and rotary motor, responsible for limiting system pressure and overloading relief functions. It effectively stabilizes the working pressure of the hydraulic circuit, avoiding damage to expensive components such as hydraulic pumps, motors, and distribution valves caused by high-pressure impacts. It is an indispensable safety component for the hydraulic systems of large-tonnage excavators.

The valve body is made of high-strength alloy steel, and the valve core undergoes precise grinding and heat treatment processes. The overall hardness is high and it is resistant to impact. It can withstand high-frequency and high-pressure impacts during the operation of large-scale machines. The sealing parts are equipped with high-quality oil-resistant rubber O-rings, with precise processing tolerances, which effectively reduce internal leakage and prevent oil leakage and pressure surges. It is suitable for complex working conditions in high-intensity construction sites such as mines and earthwork. It is resistant to high temperatures and anti-hydraulic oil corrosion, significantly extending the service life of the accessory.
