    JCB BACKHOE Main Relief Valve 25/222659

    Exclusive to JCB backhoe loaders (part no.: 25/222659), this main relief valve is a key hydraulic safety component for aftermarket maintenance, produced by Ningbo Longerfa Hydraulic Co., Ltd.—a professional manufacturer of JCB-compatible hydraulic parts (control valves, cartridge valves, etc.).
    Longerfa holds ISO9001/ISO45001 certifications and patents for JCB parts. Each 25/222659 valve undergoes 100% dynamic pressure calibration (±0.3MPa precision) and 72-hour
    leak-proof testing, fully complying with JCB OE standards to match the backhoe's hydraulic system.
    As the core pressure regulator for JCB backhoes (adapting to front loading/rear excavation), it monitors real-time pressure. t he valve core uses alloy steel with tungsten carbide coating for wear resistance;  Widely used in construction, agriculture, and municipal projects globally.
    Longerfa’s 25/222659 valve ensures stable hydraulic pressure for JCB backhoes, resisting pressure fluctuations and working reliably in extreme environments (-15℃ to 60℃, continuous heavy load).
