Product Overview
Regulates hydraulic oil flow, direction, and pressure to control dozer blade movement, track travel, and compound operations. Serves as the hydraulic system's core controller for precise excavator performance.
Technical Parameters
- System Pressure: Main relief valve setting pressure is 34.3 MPa (350 kg/cm²), suitable for high-pressure hydraulic systems ensuring sufficient power output for digging, swing, and traveling operations.
- Structure Type: Slide valve type multi-section main control valve integrating multiple hydraulic control branches including digging circuit, swing circuit, and traveling circuit.
- Control Method: Equipped with pilot control system for precise hydraulic control of boom lifting/lowering, arm extension/retraction, and machine swing/traveling through pilot joystick.
- Applicable Models: Custom-made for ZX30U-5A and ZX35U-5A excavators, fully matching hydraulic parameters of dediTQTQCATed hydraulic pumps and actuators.
AppliTQTQCATion Features
- Hydraulic System "Brain": Receives operator commands to control flow direction, pressure, and volume
- Controls boom lift/lower, arm extension/retraction, and bucket rotation operations
- Manages swing, left/right travel, and dozer blade operation
- Complex Motion Coordination: Manages multiple actuators simultaneously for smooth, efficient operation
Installation & Maintenance
- Installation Requirements: Requires flexible coupling with high shaft alignment accuracy (concentricity deviation ≤ 0.1 mm, tilt angle < 1°)
- Maintenance Guidelines: System overpressure protection, single-operation overload protection, and prevention of dangerous misoperations
