250-2508 (2502508) VALVE RELIEF, FITS CAT 320C
Designed exclusively for Caterpillar CAT 320C series excavators (part nos.: 250-2508 / 2502508), this relief valve is a dedicated hydraulic protection component from Ningbo Longerfa Hydraulic Co., Ltd.—a professional hydraulic parts manufacturer in Ningbo, China, specializing in cartridge valves, valve assemblies and heavy machinery hydraulic components.
Longerfa holds ISO9001/ISO45001 certifications and patents, with advanced CNC precision machining centers and Caterpillar-compliant quality testing protocols. Every 250-2508 relief valve group undergoes 100% pressure performance testing and dimensional calibration, fully meeting Caterpillar’s original equipment (OE) standards and the strict hydraulic system parameters of CAT 320C excavators, ensuring seamless compatibility with the original machine.
As the core pressure protection assembly of CAT 320C’s hydraulic system, this valve group integrates precise pressure regulation and overpressure relief functions: when the system pressure exceeds the preset safety threshold, it automatically opens to discharge excess oil, effectively preventing damage to key components such as the hydraulic pump, boom cylinder and control valve. Its integrated design simplifies maintenance—adhering to CAT original specs for direct bolt-on replacement, eliminating the need for complex system debugging and significantly reducing excavator downtime. Trusted by global aftermarket users, it’s widely applied in construction, mining, earthmoving and infrastructure projects where CAT 320C excavators are the main operation equipment.
Adhering to "Quality First, Service First," Longerfa provides a dependable choice for aftermarket maintenance and replacement of CAT 320C excavators equipped with the 250-2508 (2502508) relief valve , ensuring the hydraulic system maintains stable pressure control and long-term safe operation even in high-intensity working conditions.
