723-46-17600 Hydraulic Valve Pressure Relief Valve Logic Valve Bypass Valve PC200-7 PC210 PC220-7 PC230 PC300-7 Excavator Parts

Product Description

The GVO excavator relief valve, compatible with PC200-7 PC210 PC220-7 PC230 PC300-7 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 multi-way distribution valves of the PC200-7, PC210, PC220-7, PC230, and PC300-7 series excavators. It is a core pressure control component of the hydraulic system and is commonly known as the main gun. It directly manages the maximum working pressure of the entire hydraulic system of the excavator, stabilizes the output oil pressure of the main pump, and protects the multi-way valve, hydraulic pump, cylinder, motor and other hydraulic components from being damaged by excessive pressure impact. It is a key component for stabilizing the power output of the excavator. 

The valve body itself is made of high-strength alloy steel as the base material. It undergoes overall quenching and tempering heat treatment, and the valve core is precisely ground for high precision. It is combined with precise grinding of the valve port to ensure smooth movement of the valve core without sticking, and the sealing surface of the valve port is wear-resistant and impact-resistant, capable of enduring high-frequency and high-pressure oil liquid impact for a long time. The entire set of components is equipped with high-quality sealing rubber rings that are resistant to high and low temperatures and corrosion by hydraulic oil, effectively preventing internal leakage and external leakage problems. It is suitable for harsh working scenarios with large temperature differences during the day and night, high environmental dust, and complex hydraulic oil conditions. The size specifications are strictly replicated, with consistent threads, sealing positions, and valve core stroke. Installation does not require modification of the pipeline, and it can be directly replaced with the original vehicle overflow valve. The installation compatibility is high, significantly reducing maintenance and modification time.
