Ningbo Longerfa Hydraulic Co., Ltd – As the rainy season approaches, construction machinery operators and Hydraulic System maintenance teams must pay extra attention to protecting critical components such as pilot operated Unloading Valves, direct operated unloading valves, and pressure control valves from corrosion. Moisture and humidity can severely impact hydraulic systems, leading to premature wear, valve spool sticking, and reduced efficiency.

To ensure optimal performance and longevity of hydraulic valves, here are essential anti-rust maintenance tips for the rainy season.

Abnormal noises in an excavator’s hydraulic system often indicate underlying valve-related issues. These sounds—such as whining, knocking, or buzzing—can stem from problems with Relief Valve Komatsu components, Overflow Valve Relief Valve for Komatsu, or other critical hydraulic valves. As a trusted manufacturer of high-performance hydraulic solutions, Ningbo Longerfa Hydraulic Co., Ltd specializes in Komatsu Control Valve, Safety Valve Komatsu, and Komatsu PC Valve systems designed to minimize noise and maximize efficiency.

This guide explores the common valve-related causes of hydraulic noise in Komatsu excavators and provides actionable solutions to restore smooth, quiet operation.

Excavator performance heavily depends on the efficiency of its hydraulic system, particularly the valve group. When excavator movements become sluggish, the issue often lies within the Hydraulic Pressure Relief Valve or related components. As a leading manufacturer of high-quality hydraulic valves, Ningbo Longerfa Hydraulic Co., Ltd provides advanced solutions, including Excavator relief valves, Direct-Acting Relief Valves, and Pilot-Operated Relief Valves, designed to optimize hydraulic system performance.

This guide explores systematic troubleshooting methods for slow excavator valve groups, emphasizing the role of Hydraulic Pressure Relief Valve | systems in maintaining optimal pressure and flow.
