SH120 Travel Motor Relief Valve
Fit for SH120 series excavators , this travel motor relief valve is a core protective component from Ningbo Longerfa Hydraulic Co., Ltd.—a professional hydraulic parts manufacturer in Ningbo, China, specializing in cartridge valves, motor control valves and excavator travel system hydraulic accessories.
Longerfa holds ISO9001/ISO45001 certifications and patents, with advanced CNC precision machining equipment and specialized travel motor pressure testing platforms. Every SH120 travel motor relief valve undergoes 100% pressure cycle testing and leak-proof verification, fully complying with industry standards and the unique hydraulic parameters of SH120’s travel motor system, ensuring perfect matching with the original equipment’s pressure control requirements.
As the "safety barrier" of SH120’s travel motor, this relief valve monitors the hydraulic pressure of the travel system in real time: when the pressure exceeds the preset safety threshold (such as during uphill driving, heavy-load movement or emergency braking), it automatically releases excess hydraulic oil, effectively preventing damage to the travel motor, hydraulic motor shaft, reducer and pipeline components caused by overpressure. It adopts a high-wear-resistant valve core and high-pressure-resistant sealing structure, adapting to the frequent pressure fluctuations and harsh working conditions of the excavator travel system (e.g., uneven construction sites, gravel roads). Adhering to original specs for direct replacement, it eliminates the need for complex travel system debugging during maintenance, significantly shortening excavator downtime. Trusted by global aftermarket users, it’s widely applied in construction, earthmoving, road construction and mining projects where SH120 excavators are the main operation equipment.
Adhering to "Quality First, Service First," Longerfa provides a dependable choice for aftermarket maintenance and replacement of SH120 excavator travel motor systems, ensuring the travel function maintains stable speed control and long-term safe, efficient operation even in harsh working environments.
