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 PC78MR-6 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
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
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
