803278447 Relief Valve Cover Plate XCMG XDE130 Electric driving dump truck spare parts

The 803278447 relief valve cover plate can solve problems such as plate warping, oil leakage during fitting, pressure adjustment jamming, hole misalignment, end face wear, thread stripping, unstable pressure relief, seal aging, stress cracking, and loosening of fasteners. It is suitable for replacing old pressure relief valve cover plates, maintaining hydraulic pressure relief valves, original equipment manufacturer (OEM) parts, pressure relief oil circuit modification, and repairing valve cover seal damage. The integrated forged high-strength alloy cover plate + closed-loop oil-resistant sealing groove + precise pressure adjustment positioning hole structure ensures pressure resistance without deformation, tight sealing, precise pressure adjustment, corrosion and oil resistance, making it suitable for hydraulic conditions such as hydraulic pressure relief, overload unloading, and valve cavity sealing protection in engineering machinery.

Core technical parameters:

– Product Model: 803278447
– Product Name: Relief Valve Cover Plate
– Material specifications: High-pressure thickened alloy cover plate, sealing end face quenched and finely ground, not easy to wear, deform and leak oil under long-term oil pressure impact.
– Processing technology: Precision boring of original factory mounting holes, coaxial precision machining of pressure regulating holes, and direct installation and adaptation of original vehicle pressure relief valve body without damage.
– Performance and operating condition compatibility: Rated overload pressure resistance meets standards, and it is compatible with the whole machine’s hydraulic overload pressure relief control system by working with the valve body to relieve and regulate pressure.
– Structural features: Integrated pressure regulating cover structure with coaxial limiting holes to prevent assembly misalignment, abnormal pressure relief, and high-pressure oil leakage.

This product has undergone high-pressure testing, coaxial calibration, sealing pressure testing, and original factory quality inspection for compatibility with the original vehicle valve body, meeting original factory installation standards and ready to use immediately after installation. It features a sealed protective pressure relief valve cavity, precise pressure adjustment with the valve core, and balanced pressure distribution on the valve cover. It is compatible with hydraulic pressure relief valves, ensuring controllable oil pressure relief and safe and stable operation of the hydraulic system.
