SPARKLING CAT Original Valve – High-Quality Excavator Parts

The 558-5127 / 5585127 Valve GP-QDR is a genuine replacement hydraulic control valve designed for CAT D7 Track-Type Tractors. Manufactured to Caterpillar OEM standards and weighing 27KG, this original valve ensures high precision fluid control in demanding construction and earthmoving environments.

As a critical component in the hydraulic control system, the GP-QDR valve regulates the flow and pressure to various functions of the bulldozer, helping to deliver reliable and responsive operational performance. SPARKLING MACHINERY offers this valve as part of our premium product lineup—ideal for equipment owners seeking both authenticity and performance assurance.

   SPARKLING MACHINERY NEW EW145B 14528776 Sealing is a premium China-made protective component specifically engineered for EW145B wheeled excavators. As a critical barrier in the machinery’s hydraulic, fuel, and coolant systems, it prevents fluid leakage (such as hydraulic oil, fuel, or engine coolant) and blocks the ingress of dust, debris, and moisture into key components—including hydraulic cylinders, pumps, control valves, and engine housings. This safeguards system integrity, reduces costly fluid waste, and avoids damage from contamination or pressure loss, ensuring reliable operation during tasks like urban construction, road maintenance, and light earthmoving.

   Designed to original equipment standards, it maintains robust sealing performance even under EW145B’s typical working conditions: high hydraulic pressure, temperature fluctuations (-40°C to 120°C), and vibration from on-road travel and off-road operation. With optimized material elasticity and precision-molded structural design, it fits tightly to component interfaces without deformation over time. Backed by strict quality verification, it guarantees long-lasting sealing effectiveness to support uninterrupted work cycles and minimize maintenance costs linked to leaks.

SPARKLING MACHINERY NEW WA380 423-03-41310 Radiator is a dedicated cooling component for KOMATSU WA380 wheeled excavators (versatile for construction site material handling, road construction, and mining auxiliary tasks). As the core of the excavator’s cooling system, it efficiently dissipates heat from the engine and hydraulic oil to prevent overheating—ensuring stable performance during high-intensity operations like continuous loading, hauling, or equipment traction.
   Part number 423-03-41310 is a Water Tank Radiator used in the engine cooling system of the Komatsu WA380-6 wheel loader. It is a crucial component for maintaining optimal engine operating temperature by dissipating heat from the engine coolant.

Part Name: Water Tank Radiator / Engine Radiator
Application: Engine Cooling System
Compatible Machine: Specifically designed for the Komatsu WA380-6 Wheel Loader
Core Dimensions: approximately 985 mm (height) x 405 mm (width) x 100 mm (thickness).

   SPARKLING MACHINERY NEW EC120D EC135B EC140B EC140C EC140D 14531082 Check Valve is a key hydraulic anti-backflow component for 5 Volvo excavator models (construction/municipal use). 
   It prevents hydraulic oil reverse flow in circuits, protecting pumps/valves and ensuring stable function. Meeting Volvo OEM standards (14531082), it resists -30°C to 95°C temps, oil corrosion, and vibration, guaranteeing seamless compatibility and long-term reliability.
