SPARKLING EC300D Pump Regulator – Reliable Excavator Hydraulic Control

The Volvo Hydraulic Regulator (VOE 14596499) is a precision-engineered control valve integral to the K5V160DT-1E05 piston pump, used in machines like the EC300D, ECR305C, and PL3005D excavators. Built originally by Kawasaki and commonly sold as OEM or aftermarket units from trusted Chinese manufacturers, this steel body regulator weighs approximately 6.5 kg and ensures precise hydraulic flow control essential for pump stability and performance.

   SPARKLING MACHINERY NEW 7114-32560 Brake Disc EW170 is a premium China-made safety component specifically engineered for EW170 wheel excavators. As a critical part of the braking system, it works with brake pads to generate controlled friction, converting kinetic energy into heat to slow or stop the machinery, ensuring precise stopping power during operation, maneuvering, and emergency situations.

   Designed to original equipment standards, it maintains consistent heat dissipation and wear resistance, performing reliably even under frequent braking and heavy-load conditions. With optimized structural design for uniform force distribution, it adapts seamlessly to harsh working environments, from muddy construction sites to high-temperature climates. Backed by strict quality verification, it guarantees stable performance to support safe and uninterrupted machinery operation.

The ZF 4472397016 (also listed as 4472.397.016 / 4472-397-016) Bearing Pin is a high-precision component designed to provide reliable rotational alignment and structural support in ZF transmission and axle assemblies. Built from heat-treated, wear-resistant steel, this pin ensures long-term durability and smooth mechanical movement under heavy-duty conditions.

It is a perfect fit for ZF machinery applications where stability, strength, and OEM compatibility are essential. Each pin is manufactured to strict tolerances and undergoes rigorous quality control to meet or exceed OEM standards.

   The 24V DC HIGH-QUALITY 20Y-979-6771 RELAY is a premium electrical control component meticulously engineered for Komatsu Construction Equipment, specifically tailored to meet the reliable power switching demands of PC220, PC240, PC290, PC300, and PC350 Wheel Excavators. As a critical part of the machinery’s electrical system, this 24V DC relay acts as a high-performance switch, efficiently controlling the flow of electrical current to key auxiliary components (such as lights, wipers, pumps, or solenoids) with precise signal response. 
   Designed to seamlessly integrate with Komatsu’s wheel excavator electrical architecture, it delivers stable and consistent performance that enhances electrical system reliability, prevents component damage from current fluctuations, and ensures uninterrupted operation in harsh construction environments.
