Product Overview
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.
Technical Parameters
System Pressure: The main relief valve setting pressure is 34.3 MPa (350 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 arm lifting and bucket tilting).
Control Method: Equipped with pilot control system. Precise hydraulic control of boom lifting/lowering, arm extension/retraction, and machine swing/traveling is realized through the pilot joystick, with fast and sensitive operation response.
Applicable Models: Custom-made for Hyundai R330LC-9S excavators, fully matching the hydraulic parameters of its dedicated hydraulic pump, actuators (cylinders, swing motors, travel motors).
Application Features
Hydraulic System "Brain": Receives operator commands, controls flow direction, pressure and volume
Boom lift/lower, arm extension/retraction, bucket rotation
Swing, left/right travel, dozer blade operation
Complex Motion Coordination: Manages multiple actuators simultaneously for smooth operation
Installation & Maintenance
Installation Requirements: Requires a flexible coupling with high shaft alignment accuracy (concentricity deviation ≤ 0.1 mm, tilt angle < 1°)
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.
