Product Overview
This main control valve regulates hydraulic oil flow, direction, and pressure to control dozer blade movement, track travel, and compound operations. Serving as the hydraulic system's core controller, it ensures precise excavator performance across all functions.
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 cat 374F L and 390F L excavators, fully matching hydraulic parameters of dedicated hydraulic pumps and actuators.
Application Features
- Hydraulic System "Brain": Receives operator commands to control flow direction, pressure, and volume
- Primary Function Control: Controls boom lift/lower, arm extension/retraction, and bucket rotation operations
- Machine Movement Management: 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
Maintenance Guidelines: System overpressure protection, single-operation overload protection, and prevention of dangerous misoperations
