2XDYF-25-04 Hydraulic Cartridge Relief Valves
Suitable for hydraulic systems of construction machinery, industrial equipment and engineering devices (model: 2XDYF-25-04), these hydraulic cartridge relief valves are professional pressure control components from Ningbo Longerfa Hydraulic Co., Ltd.—a leading manufacturer in Ningbo, China, specializing in cartridge valves, hydraulic valve cores and integrated valve block assemblies.
Longerfa holds ISO9001/ISO45001 certifications and multiple patents for cartridge valve technology, equipped with advanced CNC precision machining equipment and specialized cartridge valve performance testing platforms. Every 2XDYF-25-04 hydraulic cartridge relief valve undergoes 100% pressure calibration and 48-hour leak-proof verification , fully complying with international hydraulic industry standards and the high-pressure working requirements of target hydraulic systems. This ensures stable performance and reliable compatibility with various valve block installations.
As core pressure protection components for hydraulic circuits, these cartridge relief valves feature a compact plug-in design that saves installation space and simplifies integration into valve blocks—ideal for equipment with limited hydraulic system layouts. During operation, they monitor system pressure in real time: when pressure exceeds the preset threshold (e.g., during heavy-load startup or sudden pressure surges), the valve core quickly opens to discharge excess oil, effectively preventing damage to hydraulic pumps, cylinders, pipelines and other key components. The valve adopts a high-wear-resistant tungsten carbide valve core and nitrided valve sleeve, ensuring long service life even under frequent pressure cycle conditions . Adhering to standard cartridge valve installation dimensions for direct replacement, it eliminates the need for valve block modification during maintenance, reducing equipment downtime by 25% on average. Trusted by global aftermarket users, it’s widely applied in construction machinery (excavators, loaders), industrial presses, plastic injection molding machines and heavy-duty transportation equipment.
Adhering to "Quality First, Service First," Longerfa provides a dependable choice for aftermarket maintenance and replacement of hydraulic systems equipped with 2XDYF-25-04 hydraulic cartridge relief valves. It ensures the hydraulic system maintains precise pressure control, avoids pressure-related failures and supports long-term stable, efficient operation in harsh working environments (such as high temperature, dust and vibration).
