4654845 Rotating Motor Relief Valve Hydraulic Safety Valve ZX200-3 ZX200-5G ZX210-3 ZX210K-3 ZX240-3 Excavator Mechanical Parts

Product Description

The GVO excavator relief valve, compatible with ZX200-3 ZX200-5G ZX210-3 ZX210K-3 ZX240-3 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 suitable for medium-sized excavators such as ZX200-3, ZX200-5G, ZX210-3, ZX210K-3, and ZX240-3. It is an important pressure protection component on the distribution valve assembly and is specifically developed and produced for the hydraulic systems of this series of Hitachi models.

The valve body is precisely machined by CNC on high-strength alloy steel and undergoes quenching and hardening treatment. The valve core and valve seat are precisely matched and ground, featuring outstanding shock resistance and high-pressure tolerance. It can continuously handle the frequently changing hydraulic loads encountered in earthwork projects and construction sites. The overflow valve is used to stabilize the hydraulic circuit pressure. When the load during excavation suddenly increases causing overpressure, the valve component quickly opens to relieve pressure, protecting the core hydraulic components such as the main hydraulic pump, multi-way valve, and hydraulic cylinder, and preventing damage to the components caused by high-pressure shock. It is equipped with high-quality oil-resistant sealing parts, which do not age or leak easily in the high-temperature hydraulic oil environment during long-term continuous operation. The pressure response is stable in both cold and hot vehicle conditions.
