Features of the Modern R300-9 Control Valve:
1. Multi-channel Integrated Structure:
Each valve body (boom, stick, bucket, swing, travel) adopts an integrated modular design, resulting in a compact size and convenient installation and maintenance.
2. Load Sensing (LS) System:
Features load feedback functionality, automatically adjusting pump flow according to load changes to reduce energy loss and improve fuel economy.
3. Electro-proportional Control:
The electro-proportional valve (EPC valve) controls the main valve spool opening based on electrical signals from the operating handle, achieving precise flow control and smooth operation.
4. Excellent Coordination of Combined Actions:
Coordination between various actions is achieved through priority valves and flow distribution logic valves, such as balancing boom lifting and swing, and stick operation.
5. Built-in Multiple Safety Valves:
Includes a main safety valve, check valve, overload protection valve, and anti-cavitation valve to prevent system overpressure, backflow, and dry suction.
6. Regeneration System Design:
During the recovery operation of the boom or bucket, the energy from the return oil is used to participate in the system's oil supply, increasing speed and reducing fuel consumption.
