SPARKLING MACHINERY NEW R210LC9BC R210LC9BH 31Q6-10050 Main Pump is a core hydraulic power component for 2 Hyundai excavator models (heavy-duty construction/mining use). It converts mechanical energy to stable high-pressure hydraulic oil, driving boom, arm, and bucket operations. The part number 31Q6-10050 is for a main hydraulic pump assembly used in various Hyundai excavators, primarily the R220LC-9 series. It is also known by the internal pump model number Kawasaki K3V112DTP.

Part Name: Main hydraulic pump (PUMP ASSY, MAIN)
OEM Part Number: 31Q6-10050 (replaced by 31Q6-10055)
Alternative MPN: K3V112DTP-1DFR-9N62
Compatible Equipment: Hyundai Excavator models R220LC-9, R220LC-9S, R220LC-9SH, R210LC-9B, and RB220LC-9S

Function: Circulates hydraulic fluid at optimal pressure to power the excavator's operations like boom movement, arm extension, and bucket functioning.

   SPARKLING MACHINERY NEW EC140B EC160B EC180B VOE14557288 Remote Control Valve is a premium China-made hydraulic control component specifically engineered for EC140B, EC160B, and EC180B excavators. As a core part of the hydraulic system’s command chain, it interprets electrical or manual control signals to regulate the flow rate, pressure, and direction of hydraulic fluid to key actuators—such as boom, arm, and bucket cylinders. This enables precise, synchronized operation of excavator functions, critical for tasks like digging, grading, and material handling in construction, mining, and infrastructure projects.

   Designed to original equipment standards, it maintains stable hydraulic control even under continuous high-pressure operation and harsh working conditions (e.g., dust, vibration, and temperature swings). With optimized valve spool machining and advanced sealing technology, it minimizes pressure loss and fluid leakage, ensuring efficient energy transfer and reducing the risk of hydraulic system failures. Backed by strict quality verification, it guarantees reliable performance to support uninterrupted machinery operation and maximize work efficiency.

   The LJ014700 relief valve is a core hydraulic pressure control component for Case CX210B and CX220C LC excavators. 

Key Features
· Precise pressure regulation to maintain hydraulic system stability (matches CX210B/CX220C LC’s working pressure requirements)
· Direct OEM fit for seamless integration without system adjustments
· Strong pressure resistance to withstand high-load hydraulic cycles
· Leak-proof design to avoid hydraulic fluid loss and performance degradation
· Adaptable to harsh job site conditions (vibration, temperature variations, dust)

Compatible Models
· Case Excavators: CX210B (supports its 36.8MPa working hydraulic pressure), CX220C LC (matches its intelligent hydraulic system pressure control needs)
· Interchangeable Part Numbers: LJ014700 (compatible with Case’s original relief valve specifications for target models)
