GVO 20220908 Pressure Relief Valve Rotating Motor Relief Valve JC-B JS210 JS220 JS230 JS240 Excavator Mechanical Parts

Product Description

The GVO excavator relief valve, compatible with JC-B JS210 JS220 JS230 JS240 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 main relief valve is suitable for the main control distribution valve of JS210, JS220, JS230, and JS240 medium-sized excavators. It is the core main pressure control valve in the entire hydraulic system of the machine, commonly known as the main cannon in the industry. It is mainly responsible for limiting the hydraulic main circuit pressure and providing overload relief protection. The relief valve directly controls the maximum working pressure of the system, determining the digging force, rotation torque, and power output of the entire machine. At the same time, it directly affects the smoothness of the compound actions and the operation feel.

The valve body is forged from high-quality alloy steel and undergoes multiple heat treatment processes. The valve body has sufficient strength and strong resistance to high-pressure impact. It is unlikely to deform or have thread damage due to long-term heavy-duty operation. The valve core is processed by high-precision mirror grinding, with precise control of the clearance. It is combined with strengthened anti-fatigue pressure-relieving springs and high-pressure sealing components. Facing the pulse pressure impact brought by earth excavation and breaker hammer operations, the valve core responds sensitively, has stable relief pressure, and has a small internal leakage even under high pressure. Even if the equipment operates continuously at high temperature for a long time, it can still maintain stable pressure regulation performance, which is very suitable for the high-intensity and uninterrupted construction environment on the construction site.
