Product Specification

KRC0184 KRC0185 LNM0429 Pressure Relief Valve Rotating Motor Relief Valve Relief Valve CX130 Cx210 Excavator Mechanical Parts

Product Description

The GVO excavator relief valve, compatible with CX130 CX210 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 designed to be compatible with the main control distribution valve of CX130 and CX210 medium-sized excavators. It is a core precision component in the hydraulic system that is responsible for pressure regulation and overload protection. It is commonly known as the "main cannon" in the industry. The relief valve controls the maximum working pressure of the entire hydraulic system, directly determining the digging force, rotation output torque, and walking power of the equipment. At the same time, it ensures the smoothness of the coordinated actions. The CX130 and CX210 models are widely used in various engineering scenarios such as urban infrastructure, earthwork excavation, landscaping, and river regulation, and are constantly operating under alternating high-pressure conditions. If the relief valve experiences valve core wear, spring fatigue, or seal failure resulting in internal leakage, it will cause a series of typical faults such as insufficient digging power, heavy-load pressure build-up, drop in engine pressure, action jitter, and inability to adjust pressure properly. It is a key component that should be prioritized for repair and replacement during major valve maintenance and hydraulic fault troubleshooting.

The valve body is forged from high-quality alloy steel and undergoes multiple quenching and tempering processes. The overall hardness of the valve body is sufficient, and its toughness is excellent, enabling it to continuously withstand the high-frequency pulsating high-pressure impact during medium-sized excavator operations. It is less likely to experience valve body deformation or thread damage during long-term operation. The valve core is processed using high-precision grinding technology, with precise control of the clearance, and is paired with strengthened anti-fatigue pressure-regulating springs and oil-resistant and anti-aging sealing kits. It responds sensitively to the valve opening and closing, and the relief and reset actions are crisp and decisive, effectively suppressing high-pressure leakage. Even if the oil temperature rises due to continuous operation for a long time, it can still maintain stable pressure regulation performance, meeting the strict requirements of all-day uninterrupted construction on construction sites.
