SPARKLING Screw‑In Spool Valve – Precision Excavator Parts

The Rexroth Relief Valve 04950403 (part no. R901102333) is a precision-engineered screw-in cartridge valve designed for hydraulic systems in excavators and industrial machinery. This robust, direct-acting spool-type valve offers pressure reducing and relieving capabilities, withstanding up to 350 bar of maximum operating pressure and supporting flow rates around 30 L/min. Constructed with quality materials and standard CAAN cavity compatibility, it ensures responsive, leak-free hydraulic control under demanding conditions.

   SPARKLING MACHINERY NEW EC300D EC250D EC220D EC235D EC160D 17253748(14613051) Pressure Sensor is a critical hydraulic/pneumatic monitoring component for Volvo EC300D, EC250D, EC220D, EC235D, and EC160D excavators (widely used in construction, mining, and infrastructure projects). As the "pressure guardian", it real-time detects hydraulic system pressure (e.g., boom, bucket circuits) or pneumatic pressure—alerting operators to abnormal pressure spikes/drops during tasks like digging, lifting, and rock breaking, while preventing component damage from overpressure and ensuring stable equipment operation.
   Meeting Volvo OEM standards (part nos. 17253748/14613051), it endures -30°C to 100°C temperatures, resists oil corrosion and vibration, and guarantees accurate pressure signal output. Strict testing ensures seamless compatibility with the five Volvo models and long-term pressure monitoring reliability.

   SPARKLING MACHINERY NEW R260LC9S R290LC9 R290LC9MH R320LC7 R330LC9S XKBF-01503 Valve Assy is a dedicated hydraulic control assembly for Hyundai R260LC9S, R290LC9, R290LC9MH, R320LC7, and R330LC9S crawler excavators (widely used in heavy construction, mining, and infrastructure projects). As the "hydraulic control center" of the excavator, it integrates multiple valves to regulate oil flow, pressure, and direction—powering key functions like boom lifting, bucket digging, and swing movements, ensuring smooth and precise operation during high-intensity tasks.
   Meeting Hyundai OEM standards (part no. XKBF-01503), it endures 32 MPa working pressure, -30°C to 95°C temperatures, resists oil corrosion and vibration, and maintains leak-free performance. Strict testing guarantees seamless compatibility with the five Hyundai models and long-term hydraulic system stability

   SPARKLING MACHINERY NEW R140W7 R200W7 ZGAQ-02045 Disc-Clutch is a premium China-made transmission component specifically engineered for R140W7 and R200W7 wheel excavators. As a critical part of the power transmission system, it enables smooth engagement and disengagement of mechanical power, regulating torque transfer between the engine and drivetrain to ensure precise control during acceleration, deceleration, and operational adjustments.

   Designed to original equipment standards, it maintains consistent friction performance and heat resistance, operating reliably even under high-load conditions and continuous use. With optimized structural design for efficient power transmission, it adapts seamlessly to harsh working environments, from dusty construction sites to rugged terrain. Backed by strict quality verification, it guarantees stable performance to support uninterrupted machinery operation.
