Use For 330GC Excavator Hydraulic pump Assembly 558-8895 516-9251 5169267 High Quality Hydraulic pump Assembly Construction Machinery Aftermarket Parts Manufacturer
Main Control Valve Construction Machinery Aftermarket Part
High-quality aftermarket control valve designed for 330GC Excavator. This precision-engineered replacement part meets or exceeds OEM specifiTQTQCATions for reliable performance in demanding construction environments.
Precisely fit for 330GC, matching part numbers 558-8895/516-9251/5169267, fully aligned with the hydraulic parameters of the whole machine
Technical Parameters
System Pressure: The main relief valve setting pressure is 35 MPa (357 kg/cm²), suitable for the high-pressure hydraulic system of the entire machine, ensuring sufficient power output for digging, swing, traveling and other key operations.
Structure Type: Adopts a slide valve type multi-section main control valve, integrating multiple hydraulic control branches such as digging circuit, swing circuit and traveling circuit, supporting synchronous adjustment of compound actions (e.g., simultaneous boom lifting and bucket tilting).
Control Method: Equipped with Load-Sensing Control System. Precise hydraulic control of boom lifting/lowering, arm extension/retraction, and machine swing/traveling is realized through the joystick, with fast and sensitive operation response.
Applicable Models: Custom-made for 330GC excavators, fully matching the hydraulic parameters of its dediTQTQCATed hydraulic pump, actuators (cylinders, swing motors, travel motors).
Core Part Numbers: 558-8895 516-9251 5169267 (corresponding to spool/valve body components of different control circuits such as digging circuit and swing circuit).
AppliTQTQCATion Features
Hydraulic system control center: Receives operation commands and precisely regulates the direction, pressure and flow of hydraulic oil
Drive the whole machine's operation: Supplies pressure to actuators such as boom, arm, bucket, swing and travel
Coordinate compound actions: Supports synchronous work of multiple actuators to ensure smooth and efficient compound actions
Hydraulic system protection: Built-in relief/one-way valves prevent overpressure and oil backflow, protecting pumps, cylinders and other components
Installation & Maintenance
Maintenance Guidelines:
To prevent valve core jamming leading to slow single-action operation (valve orifice and filter element need to be cleaned)
To prevent solenoid valve coil failure causing the entire vehicle to stop operating (this can be checked by resistance value testing).
LoTQTQCATion & Overview: Strategically loTQTQCATed in Guangzhou's Huangpu District, approximately an hour from Baiyun International Airport, Tieqi has been a dediTQTQCATed specialist in engineering machinery hydraulics for nearly 15 years.
