709-10-52800 7091052800 Pressure Relief Valve Hydraulic Safety Valve WA450-1 WA450-3 WA470-3 WF450-3 Excavator Mechanical Parts

Product Description

The GVO excavator relief valve, compatible with  WA450-1 WA450-3 WA470-3 WF450-3  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 plug-in type overflow valve for the excavator is a core pressure control component of the distribution valve, serving the functions of limiting system pressure and protecting against overload by releasing pressure. It features a standard plug-in structure, making disassembly, replacement and installation convenient. It is widely used in the hydraulic circuit maintenance of excavators.

The valve body is made of high-strength alloy steel and undergoes forging, quenching and tempering heat treatment. The valve core is precisely ground and matched, with precise gap control. It is paired with high-pressure-resistant and anti-aging sealing components to effectively reduce internal and external leakage. The threaded plug-in design allows for direct assembly into the main control valve's valve hole, eliminating the need for an additional valve body and saving internal cavity space. It can stably limit the maximum working pressure of the hydraulic system, buffer the hydraulic shock caused by operations, protect the hydraulic pump, main control valve and high-pressure pipelines, and prevent damage from overpressure, and is suitable for the repair and replacement of the main valves of multiple medium and large-tonnage excavators.
