   And first—thank you so sincerely, from the bottom of our hearts, for choosing SPARKLING MACHINERY’s LJ015170 Relief Valve for your Case CX350B or CX290B excavator! Your trust isn’t just a purchase to us; it’s the driving force behind our commitment to meeting Case’s strict standards for hydraulic safety components. This relief valve isn’t just a spare part—it’s your excavator’s “hydraulic pressure guardian”; a faulty one can cause costly component damage or unexpected system shutdowns. Ours is engineered to fit and perform exactly like Case’s original, so you can count on it fully. Let’s dive into why it’s the perfect match for your machine.

   Why choose the SPARKLING NEW CX350B, CX290B LJ015170 Relief Valve?
   - Direct-fit compatibility: Exclusively tailored to match the exact mounting dimensions, port sizes, connection thread specs, and seal configurations of Case CX350B/CX290B hydraulic systems. Marked with genuine part number LJ015170, it aligns perfectly with existing hydraulic pipelines and control units—no drilling, port modification, or adapter use is needed. This cuts replacement downtime by up to 30%, getting your Case excavator back to high-intensity work faster.
   - Precision control: Features ultra-accurate pressure setting (pressure deviation <1%) and fast relief response (<0.03 seconds), strictly calibrated to Case’s original hydraulic parameters. It instantly releases excess pressure when the system exceeds safe limits (e.g., during CX350B’s heavy bucket loading), protecting hydraulic pumps and cylinders while keeping non-affected functions running stably.
   - Rigorous quality: Undergoes 18+ strict quality tests tailored to Case excavator operating conditions, including 32 MPa pressure relief trials (zero leakage after relief), high-low temperature cycle tests (-30°C to 95°C, 700+ cycles), durability verification (10,000+ relief cycles without performance drop), and oil compatibility trials (with Case-approved high-pressure hydraulic oil). It withstands dusty construction sites, rocky mining zones, and continuous vibration without performance degradation.
   - Professional support: Backed by a dedicated technical team with deep expertise in Case CX350B/CX290B hydraulic systems and relief valve maintenance. We offer 7×24 online assistance, including step-by-step installation guides (with model-specific mounting torque charts and pressure calibration tips), maintenance recommendations (e.g., periodic pressure inspection, valve cleaning), and troubleshooting for issues like delayed relief, pressure drift, or oil leaks. Our team ensures an average response time of <2 hours.
   - Cost-effective reliability: Delivers Case OEM-level performance at a competitive price, avoiding the premium of original dealer parts for relief valves. Its durable construction (high-strength alloy valve body, wear-resistant internal spools) extends service life by up to 40% compared to generic alternatives, reducing long-term replacement costs by 25%. It also minimizes unplanned downtime caused by valve failure—preventing costly hydraulic system overhauls and delays in construction or mining projects.
